Nine more seed leaves move to 20-coll.clj (verified leaf-by-leaf: defn +
core-bindings entry only, no internal callers). fnil is upgraded to Clojure's
canonical 2/3/4-arity — it patches only the first 1-3 arguments; the old
kernel fn patched every position it had a default for, which Clojure does
not. The rest carry their kernel semantics over unchanged (bigdec is a
double, numerator/denominator throw, supers is #{}, munge rewrites dashes).
16 new spec rows incl. the fnil arity-contract cases. Gate green:
conformance 326x3, suite 4577, full jpm test (2:18 — first full run with the
ctx image cache on main).
*in*, read-line, read, with-in-str, and line-seq land as a new overlay IO
tier (core/50-io.clj). *in* is a dynamic var holding a reader — a plain map
of two closures, :read-line-fn (next line, nil at EOF) and :read-fn (next
form, advancing past exactly that form). The default *in* reads real stdin
with a shared leftover buffer, so read and read-line interleave correctly;
with-in-str rebinds *in* to a string reader over one atom-held buffer —
(read) consumes its form, a following (read-line) returns the rest of that
line, as in Clojure. read has the 0/1/3 arities (EOF throws, or returns
eof-value when eof-error? is false).
The Janet seed grows two seams next to read-string: __stdin-read-line (one
line off stdin, newline stripped) and __parse-next (one form off a string ->
[form rest], nil at end of input) — and loses the line-seq stub.
Two traps hit and documented for future tiers: a map LITERAL with :jolt/type
as a key is read as a tagged form (don't tag overlay value maps), and a
leftover seed stub holding the same name breaks direct-linked self-recursion
— the overlay line-seq's recursive call bound to the stub's root, truncating
after one line. The stub's string-splitting behavior is kept as a documented
extension.
20 new io-spec rows (read-line EOF/interleave, read arities + eval round-trip,
line-seq incl. real-stdin paths). Gate green: conformance 326x3, suite 4577,
full jpm test.
sorted-map/sorted-map-by/sorted-set/sorted-set-by/sorted?/sorted-map?/
sorted-set?/subseq/rsubseq now live in their own overlay tier (25-sorted.clj).
A sorted coll is a tagged host table with a comparator-ordered :entries
vector, a 3-way :cmp, and the tier's op implementations ATTACHED to the value
(:ops map): the seed's conj/assoc/get/seq/count/... branches are each a
one-line call through (coll :ops), so the ops travel with the value — correct
across contexts, forks, and AOT images, no module-level hooks to re-wire.
The host surface grows by three minimal value primitives: jolt.host/
tagged-table, ref-put! (already there), and ref-get — a raw field read,
because plain get on a sorted coll IS the comparator lookup and reading
:entries with it recurses.
This fixes a pile of Clojure-correctness gaps the Janet kernel had:
- lookup/membership now go through the COMPARATOR: (contains? (sorted-set 1)
1.0) was a deep= scan, (conj (sorted-set 1) 1.0) and assoc of a
comparator-equal key now no-op/replace as in Clojure
- equality is representation-agnostic: (= (sorted-map :a 1) {:a 1}) and
(= (sorted-set 1 2) #{1 2}) were false
- iteration was broken: (map inc (sorted-set 3 1 2)) errored
(realize-for-iteration and coll->cells had no sorted branches)
- empty?/empty saw the host wrapper, not the collection: (empty? (sorted-map))
was false, (empty sc) returned a bare table; it now keeps the comparator
- sorted colls canonicalize as map keys; comparator fns may be boolean
predicates or 3-way (Clojure's fn->comparator)
- sorted-map throws on odd kv count; conj nil is a no-op
Also fixes jolt-h86 en passant: into-conj had no branch for sets (or sorted
colls) and silently returned the target unchanged — (into #{} [:a :b]) was
#{}. The fallback now folds conj. Regression rows in sets-spec.
sorted-spec grows to 77 rows (comparator-based membership, equality,
empty/rseq/printing, seq-fn interop, subseq/rsubseq on maps). Gate green:
conformance 326x3, suite 4577 (vs 4566 prior — the battery gained rows),
sorted+sets specs, full jpm test, bench at parity with main back-to-back
(4521ms vs 4619ms TOTAL under identical load).
Pins down what a transient is in Jolt (tagged table over a native Janet
array/table, canonical-keyed for maps/sets), where behavior deviates from the
JVM (O(n) transient/persistent! edges with O(1) native ops between, no
owner-thread check — same as Clojure 1.7+, transient-of-list leniency), and
the three reasons the machinery is seed-resident rather than a migration
candidate: it IS the mutation kernel, it sits under the seed's own dispatch,
and the value layer is declared irreducible. Exists so the kernel-shrink
ladder (jolt-tzo) doesn't revisit transients every round.
init in compile mode is ~2.4 s (tier loading, analyzer self-compile, macro
recompilation), paid by every process that builds a ctx from source — each
jpm-test file, embedders, workers. init-cached marshals the built ctx to a
disk image (same root-env dicts as snapshot/fork) and later processes
unmarshal it in ~5 ms, any process: nothing from the baking process is
needed at load.
The cache key fingerprints the embedded .clj stdlib (which covers jolt-core:
analyzer, IR, core tiers), the .janet seed sources next to the module, the
janet version, the init opts, and the env knobs that shape a ctx (JOLT_PATH/
MUTABLE/AOT_CORE/FEATURES) — any change rebuilds. Corrupt or non-ctx images
fall back to a rebuild (unmarshal of garbage can 'succeed' with a scalar, so
the shape is checked, not just the throw). Writes are atomic (tmp + rename)
so racing cold starts never publish a torn image. JOLT_NO_IMAGE_CACHE=1
opts out; JOLT_IMAGE_CACHE_DIR overrides the location (default TMPDIR).
Test consumers switch to init-cached (harness, suite-worker, conformance,
the behavioral unit/integration tests); tests that validate the bootstrap
itself (bootstrap-fixpoint, staged-bootstrap, aot round-trip, direct-linking)
and the deps tests (tmp-dir :paths would fragment the key) keep real init.
Full jpm test: 2:46 -> 1:58 (~29%). New ctx-image-test covers cold/warm,
cross-process load (subprocess runs defn/redef/macros/protocols/multimethods
off the baked image), per-opts keying, and corrupt-image fallback.
The 1104-line Janet bootstrap compiler existed to build jolt.ir/jolt.analyzer
and the kernel tier before the self-hosted analyzer could exist. It is
replaced by the interpreter + one fixpoint turn:
1. bootstrap-load-source loads the compiler sources INTERPRETED (the
evaluator can run the analyzer — it always could).
2. After the overlay is up, self-compile-compiler! re-runs the kernel tier,
jolt.ir, and jolt.analyzer through the SELF-HOSTED pipeline — the
interpreted analyzer compiles itself, and steady state runs compiled with
no bootstrap compiler involved.
Measured: init {:compile? true} 1093 -> ~2400 ms (the one-time interpreted
pass + self-compilation), but steady-state compilation is 2.8x FASTER
(100 forms: 134 -> 48 ms) — the self-hosted pipeline emits better code than
the bootstrap did. An AOT image for init cost is future work (aot.janet's
machinery is the natural vehicle).
The bootstrap's runtime kernel moves to backend.janet (jolt-runtime-env,
ctx-janet-env, build-map-literal); aot imports it from there. The
uncompilable-error? punt check unwraps the interpreter's exception struct
(the interpreted analyzer's throw arrives wrapped). compile-string/
compile-file (the bootstrap's source-text emitter API, no callers outside
the bootstrap's own unit test) are removed with it, as is compiler-test.
Gate green across everything incl. fixpoint stage1==2==3, AOT round-trip,
uberscript, CLI; conformance 326x3; suite 4566 >= 4540; bench in band.
make-hierarchy/derive/underive/isa?/parents/ancestors/descendants are now
Clojure in the overlay — Clojure's own pure-map implementation: a hierarchy
is {:parents {tag #{..}} :ancestors {..} :descendants {..}}, the 3-arity
forms are PURE (derive returns a new hierarchy), and the 1/2-arity forms swap
a private global-hierarchy atom.
This fixes three correctness gaps the Janet kernel had: multi-parent derive
(the kernel's :parents held a single parent per tag), TRANSITIVE descendants
(the kernel tracked direct children only), and vector-pair isa?
((isa? [child1 child2] [parent1 parent2])). Cyclic and duplicate derives now
behave like Clojure (throw / no-op).
Multimethod dispatch was the kernel's only internal caller: defmulti-setup's
dispatch closure now calls the overlay's isa? through a lazily-resolved var
(cached per multimethod); a :hierarchy option is an atom (deref per dispatch,
matching Clojure's var semantics) or a plain hierarchy map. The Janet kernel
(types.janet) and the core-* wrappers are deleted.
20 new hierarchy spec rows (pure 3-arity incl. cycle/duplicate edges, global
+ dispatch incl. custom :hierarchy atoms). Gate green: conformance 326x3,
suite 4566 >= 4540, all batteries, bench in the session band.
The representation predicates (sequential?/associative?/counted?/indexed?/
reversible?/seqable?, boolean?/double?/float?/infinite?, the qualified/simple
ident predicates), the realization boundaries doall/dorun, list*, find,
realized?/force, pop, the print-str family, and rand-nth/random-sample are
now Clojure in 20-coll, expressed over the overlay's own predicates and
primitives — no Janet representations referenced.
Several got MORE correct in the move: dorun honors its bounded-n arity (the
seed ignored n); find works on vectors by index (contains? gives it free);
indexed? no longer claims seq results; seqable? no longer claims arbitrary
tagged tables (atoms were "seqable"); realized? reads the tagged slots via
the established get pattern.
Seed: 3427 -> ~3200 lines, 371 -> ~345 core-* fns. Gate green (conformance
326x3, suite 4569 >= 4540, stdlib battery, all specs+unit); bench in noise.
*ns* is interned in clojure.core holding the current NAMESPACE OBJECT, kept
in sync by ctx-set-current-ns through a var table cached on the env (one
table put on the hot path; core-bench A/B neutral). A thread binding
(binding [*ns* ...]) shadows the root through var-get as usual. in-ns now
returns the namespace object (Clojure); str renders a namespace as its name
and pr-str as #namespace[name]. The ns-designator helper accepts namespace
objects (they are tagged STRUCTS — the old table?-based check never matched
them), so (ns-aliases *ns*) / (ns-unalias *ns* 'a) work — SCI and the jank
syntax-quote corpus use exactly that shape.
Known divergence (documented): inside an interpreted fn, *ns* reflects the
fn's defining ns (jolt's resolution model rebinds current-ns per call);
top-level and load-time reads match Clojure.
Gate green (conformance 326x3, suite 4572 >= 4540, all batteries,
specs+unit +8 *ns* rows); bench neutral.
The names turn 2a's leak removal exposed as honestly missing, now proper:
- slurp/spit/flush (host-classified): path-based IO over Janet files; spit
takes :append; flush flushes *out*. printf prints formatted (no newline)
over the existing format. file-seq walks paths via two host dir primitives
through the overlay's tree-seq.
- ns-map / ns-unmap / ns-refers (ctx fns). ns-refers required fixing the
refer MODEL: refer/use/:refer now map the SOURCE VAR into the target ns
(the Clojure model) instead of copying its value into a new var — so
source-ns redefinitions propagate, the :macro flag travels for free, and
refers are identifiable by the var's home :ns.
- Thread-binding family: with-bindings*/with-bindings, bound-fn*/bound-fn,
bound?, thread-bound?, get-thread-bindings. The captured binding map is a
Janet struct keyed by the var tables — the exact frame representation
var-get reads — so it re-pushes correctly (a phm frame is invisible to
var lookup).
- load-string and eval interned as VALUES at the api layer (they need the
loader's compile-or-interpret routing); the eval special form still
handles direct calls.
Suite 4532 -> 4572 (baseline floor 4540 across timeout variance, clean 86),
conformance 326x3, stdlib battery, all specs+unit (+21 turn-2b rows).
Coverage: missing-portable 27 -> 10 (left: the *in*-model readers, the
with-local-vars/with-precision/extenders tail).
resolve-sym's last resort silently resolved any unknown Clojure symbol
against Janet's root environment — leaking Janet builtins with JANET
semantics into Clojure code: (type 1) was Janet's :number, (gensym) returned
Janet symbols (the long-documented (symbol (str (gensym))) macro landmine
existed BECAUSE of this), compare/slurp/int?/any? likewise. The explicit
janet/ prefix is the deliberate interop channel; the implicit fallback is
gone — an unresolved symbol is an error.
What the leak was masking, now proper interned vars:
- gensym: jolt's own (already existed, never interned) — returns real jolt
symbols; the macro landmine is dead
- compare: full Clojure total order (nil-first, numbers, strings, keywords,
symbols by ns/name, booleans, chars, uuid/inst, vectors by length then
elementwise; cross-type throws)
- type: :type metadata override, deftype/record tag as symbol, else a
taxonomy keyword (host-classified)
- int?: core-integer? — which had a latent bug the leak hid: (integer?
##Inf) was true (floor of inf is inf); NaN/infinities now excluded
- any?: constantly true (Clojure 1.9; SCI's namespaces.cljc needs it)
- jolt.interop/janet-type now uses the explicit (janet/type x) channel
- evaluator-test uses init (a bare make-ctx resolved EVERYTHING via the leak)
Suite 4470 -> 4532+ pass / 86-87 clean (proper compare unlocks the sort
files); baselines raised. Conformance 326x3 (+5 rows), +22 predicate spec
rows, stdlib battery green, all specs+unit. Coverage dashboard now counts
previously-leak-resolvable names honestly (missing-portable 19 -> 27).
CI caught what the local per-change gate missed (clojure-stdlib-suite-test
wasn't in the habitual gate list): strict map? (PR #28) correctly stopped
treating tagged structs as maps, which silently disabled edn->value's
(and (map? x) (= :jolt/set ...)) set-form branch — edn/read-string returned
raw reader forms for #{...}. Reader FORMS are now detected by :jolt/type
directly, never via map?.
While here, EDN's built-in tagged elements are applied properly: a
:jolt/tagged form routes through the registered data reader (__read-tagged,
a ctx-capturing core fn over :data-readers), so (edn/read-string "#uuid ...")
yields a real UUID value and #inst an instant — per the EDN spec. The
read_string battery goes 47 -> 50 (above the old 49 baseline: the uuid
asserts pass now); baseline raised to 50.
#inst (jolt-rnh): an instant is an immutable tagged struct
{:jolt/type :jolt/inst :ms <epoch-millis>} — equality and map-key hashing by
INSTANT, so different offsets denoting the same moment are =. The reader
parses RFC3339 with Clojure's partial-timestamp defaults (#inst "2020" is
2020-01-01T00:00:00.000Z) and errors on malformed input; inst?/inst-ms in
the overlay; pr-str prints the canonical
#inst "yyyy-MM-ddThh:mm:ss.fff-00:00" and round-trips; str gives the bare
RFC3339 string. Self-evaluating in the evaluator (like uuid/chars).
Syntax-quote (jolt-l2a): a syntax-quoted self-evaluating literal (string,
number, boolean, nil, keyword, char) collapses to the literal at READ time,
matching Clojure's reader — so nested/adjacent backticks over literals are
inert: (= "meow" ```"meow") is true (jank pass-adjacent). Symbols still
qualify and collections still template. General nested syntax-quote over
non-literals remains UNVERIFIED in spec S25.
Tests: inst-spec (18 cases incl. partial defaults, offsets, round-trip),
+10 literal-collapse reader rows, +5 conformance rows (321x3). Spec
02-reader S20/S25 updated to normative. Suite stable 4470/86.
One documentation root: the prose docs (building-and-deps, self-hosting
architecture/compiler, tools-deps, grammar.ebnf) join the spec and RFCs under
docs/. References in README and deps-conformance-test updated.
jolt no longer satisfies :clj in reader conditionals. The shortcut was a
measured net liability: :clj branches carry JVM interop and JVM-specific
test expectations jolt fails, and they shadowed :default branches jolt
passes. A/B over the suite: clj,default = 4967 assertions / 4324 pass / 119
errors; jolt,default = 5069 / 4470 / 81 (+146 pass, -38 errors, +8 clean
files). Baselines raised to 4470/86.
Matching is now by CLAUSE order like Clojure — the first clause whose key is
in the feature set wins (#?(:default 5 :clj 6) is 5 everywhere); the old code
scanned for :clj first, then :default, regardless of position.
Foreign clj-targeted libraries are a property of the LOADING CONTEXT, not the
platform: reader-features-set! opts a load into a compatibility set, and the
SCI bootstrap/runtime tests load SCI under ["jolt" "clj" "default"] (its
.cljc selects implementations via :clj with no :jolt branches).
JOLT_FEATURES remains the process-wide override.
RFC 0002 records the decision with the measured data; spec 02-reader S18 is
now normative (clause order, documented feature set, per-context override).
Reader tests updated to the portable set + an opt-in round-trip.
The lexical-syntax chapter, granularity modeled on jank's 62-file
per-construct reader corpus: token grammar (whitespace/comments, collections
with read-time duplicate checks, numbers incl. the N/M tower question,
symbols/keywords incl. ::auto-resolution, strings/chars), the quote-family
sugars, the full #-dispatch catalog with normative entries (anonymous fn
%-derivation, discard composition, reader conditionals, symbolic floats,
tagged literals), and the syntax-quote contract (core/alias/current-ns
qualification, template-stable gensyms, ~' idiom, distribution through
collections).
Adapting the corpus surfaced and filed three findings, recorded as labeled
divergences/UNVERIFIED in the chapter: nested syntax-quote doesn't collapse
(S25, (= "meow" ```"meow") is false), #inst reads as a bare string (identity
data reader, no instant type), and jolt satisfies :clj in reader
conditionals (feature-key policy under review).
reader-forms-spec gains 11 chapter-cited rows (discard stacking, ##Inf/
##-Inf/##NaN, :default conditionals, qualified var-quote identity, gensym
stability within vs across templates) — all passing.
Fifteen vars from the spec coverage gap (docs/spec/coverage.md):
parse-long/parse-double/parse-boolean (strict validation; scan-number alone
accepts 0x10), newline, current-time-ms (host clock for time), update-keys/
update-vals (PHM base, collisions last-wins), partitionv/partitionv-all/
splitv-at (lazy seqs of vectors; splitv-at's tail stays a seq, matching the
reference), with-redefs/with-redefs-fn (roots restored on throw), time,
macroexpand (expand-1 to fixpoint), alias/ns-unalias (write BOTH alias stores
— require :as uses string-keyed :imports while ns-aliases reads :aliases;
split filed), ns-publics (symbol-keyed map; publics == interns, no privacy).
Three pre-existing bugs fixed along the way:
- (partition n step pad coll) misparsed pad as the coll and returned ()
- (require 'bare.symbol) rejected — only vector specs were accepted
- analyze-form leaked the interpreted analyzer's ns on a punt: a throw out of
the analyzer left current-ns=jolt.analyzer and :compile-ns set, so the
fallback interpretation resolved user vars against the wrong namespace
(bit (var user-sym) under compile mode)
And one overlay-authoring landmine documented in-code: a 20-coll fn must not
use 30-macros macros (with-redefs-fn's dotimes compiled as a forward ref that
resolved to the macro fn at runtime) — loop/recur instead.
Gate: conformance 316x3 (+14 rows), suite 4324 pass / 78 clean (was 4081/72;
parse_*/update_* files now contribute), baselines raised, all specs+unit,
fixpoint, self-host, sci, staged. Coverage: missing-portable 35 -> 20.
RFC 0001 proposes a normative, implementation-independent Clojure language
spec (the reader, evaluation model, special forms, data types, seq/laziness
contracts, namespaces/vars, and the portable clojure.core surface) to the
standard of R7RS/Racket — Clojure has none, and every alternative
implementation re-derives semantics from the reference and folklore. The
spec is executable-first: every numbered normative statement cites its
conformance test or is marked UNVERIFIED.
docs/spec/ carries the front matter (conformance terms, entry format, host
classification), the special-form catalog with worked normative entries for
if and let*, the core-library entry format with worked entries for first,
reduce, and parse-uuid, and a generated coverage dashboard over the 694-var
ClojureDocs inventory (tools/spec_coverage.py cross-references the surface
against jolt's interned+resolvable vars and the test suites).
Measured baseline: 380 implemented+tested, 154 implemented-untested, 35
portable-but-missing (filed), 22 resolvable-but-not-interned (filed — seed
fns invisible to resolve/ns-publics), rest classified host/JVM/concurrency.
map? treated ANY struct as a map, so (map? 'sym), (map? \a), and
(map? (random-uuid)) were all true; coll? had the same wart. Meanwhile both
were FALSE for sorted maps (and coll? for sorted sets and records), which are
collections in Clojure. Now: a map is a plain struct literal, a phm, a sorted
map, or a record; coll? additionally includes sorted sets. Tagged structs
(anything with :jolt/type) are values.
The loose-map? dependents (destructure's clause ordering, defn's attr-map
guard) already guarded with symbol? first, so nothing relied on the wart —
full gate green, and the suite gained: 4074 -> 4081 pass / 72 clean files
(map_qmark/coll_qmark assertions now correct); baselines raised. 22 new
strictness spec cases.
uuid support was broken end to end (jolt-6s2): random-uuid built malformed
strings ((string/format "%x") with no zero-padding, so hex groups came out
short, and no variant bits), uuid? was hardcoded false, the #uuid data reader
was identity (bare string), and parse-uuid didn't exist. Nothing tested it.
A UUID is now an immutable tagged struct {:jolt/type :jolt/uuid :str <lower>}
(make-uuid, types.janet) — struct value equality gives case-insensitive = and
map-key/set hashing for free, and the evaluator treats it as self-evaluating
(like chars). random-uuid emits a correct RFC 4122 v4 (zero-padded 8-4-4-4-12,
version nibble 4, variant 8-b). parse-uuid validates the canonical shape,
returns nil on a bad string, throws on a non-string (Clojure 1.11). uuid? is
an overlay tag predicate. str renders the bare string; pr-str renders
#uuid "..." and round-trips.
Tests: uuid-spec (30 cases: format, parse edge cases from the suite, value
semantics, reader literal), 6 conformance cases x3 modes. The suite's
parse_uuid/random_uuid/uuid_qmark files now contribute: 4049 -> 4074 pass,
71 clean files; baselines raised.
With tiers 6a-6c done, the interpreter punt surface is down to the frozen
curated set: defmacro, set!, letfn (needs letrec IR), eval, the host-interop
heads (./new/Foo./.method), and the JVM-compat stubs (gen-class,
monitor-enter/exit). must-punt now enumerates it exhaustively — growing the
list is a regression (lost compiler coverage); shrinking it is progress.
This is the Stage 2 definition of done for the special-names tail.
prefer-method/remove-method/remove-all-methods/get-method/methods become
overlay macros over ctx-capturing *-setup fns (a multimethod's method table
lives on its VAR, so the name passes quoted — the defmulti/defmethod shape).
instance? likewise (class names don't evaluate to values); satisfies? is a
plain ctx-capturing fn (evaluated args). locking and defonce become overlay
macros — locking now also evaluates the monitor expr (the old arm skipped it
and any body form past the first); defonce keeps the existing-root check.
read-string and macroexpand-1 are ctx-capturing fns.
Removed all eleven from the evaluator special arms + special-symbol?,
host_iface special-names, and compiler uncompilable-heads. evaluator-test's
locking/instance? cases use init now (overlay macros need the full env).
Surfaced pre-existing (filed): multimethod dispatch records prefer-method
preferences on the var but never consults them in ambiguous isa dispatch.
Gate: conformance 296x3 (+11 tier-6c cases), fallback-zero 73/3, fixpoint,

create-ns/remove-ns/find-ns/all-ns/the-ns/ns-interns/ns-aliases/ns-imports/
ns-resolve/resolve/refer become ctx-capturing clojure.core fns
(install-stateful-fns!) with evaluated-arg Clojure semantics, replacing
interpreter special arms that were loose: the-ns/ns-interns/ns-aliases/
ns-imports ignored their argument (always current ns), create-ns/remove-ns/
ns-resolve took theirs unevaluated. The optional-arg forms still default to
the current ns, preserving the prior 0-arg behavior. refer previously had a
special-names entry but NO interpreter arm — it errored everywhere; it now
refers the named ns's public vars (use-impl), :only/:exclude filters not yet
honored. ns-resolve does its lookup directly: types/ns-resolve keys ns-find
with the symbol struct instead of its name string and never finds anything.
Removed all of them from the evaluator arms, host_iface special-names, and
compiler uncompilable-heads (use/ns/require/in-ns stay punted in the bootstrap
compiler — it builds analyzer.clj, whose ns forms need the interpreter).

var-get/var-set/var?/alter-var-root/alter-meta!/reset-meta! already had plain
core-bindings wrappers — the interpreter special arms shadowed them (and the
arm's alter-var-root silently dropped rest args, which the core wrapper
handles). find-var/intern need the ctx, so they join install-stateful-fns! as
ctx-capturing clojure.core fns; the old core-intern binding was a do-nothing
stub. Removed the eight from the evaluator special arms + special-symbol?,
host_iface special-names, and compiler uncompilable-heads.
