Adds :vector/:map/:set (emit-ordered, left-to-right element eval) and :quote to
the portable Clojure emitter. Collection-literal nodes carry already-analyzed IR
items so they just recurse; quote walks the RAW reader form.
emit-quoted walks the reader form via the jolt.host form-* contract (form-list?/
form-elements/form-vec-items/form-map-pairs/form-set-items/form-sym-*), the same
portable seam the analyzer uses — not host-native predicates, so it works
unchanged whether the form came from the Janet reader or the Chez reader. Reader
forms are raw host representations (Janet list=array, vec=tuple), so native
list?/vector? would not see them; the contract is the correct abstraction and
keeps the emitter host-neutral. Quoted-symbol metadata and def-meta still defer
to inc 3.
Surfaced a latent Janet-host bug (jolt-tg9s): (quote #{...}) evaluates to the raw
reader form instead of a reconstructed set, so (contains? (quote #{:p :q}) :p) is
false on build/jolt. The Chez emitter is correct (real Clojure: true); the parity
test asserts the verified value for those two cases.
Gate: emit-parity 42/42 (incl vector/map/set literals, coll/kw-as-fn, quoted
list/vec/map/set/symbol/nested). emit-test 331/331, conformance 355x3. jolt-7jvp.
First spine increment of self-hosting the compiler on Chez. The IR->Scheme
emitter is host/chez/emit.janet (Janet); to get the analyzer emitting its own
code on Chez with no Janet, the emitter logic has to be portable Clojure that
cross-compiles and runs on Chez itself.
jolt-core/jolt/backend-scheme.clj ports the core ops: const/local/var/the-var/
if/do/let/loop/recur/invoke (+ native-ops)/fn/def, plus the chez-str-lit/flonum/
munge/truthy-elision helpers and prelude-mode. Output is Scheme source text, op-
for-op with emit.janet. recur-target/known-procs are dynamic vars (auto-restore,
no throw-leak). Quote, collection literals, try/throw, host interop, regex/inst/
uuid and program assembly come in later increments (they throw not-yet-ported).
Gate: test/chez/emit-parity.janet loads the Clojure emitter interpreted on the
Janet host and runs each case through it -> Chez -> compares to the Janet CLI
oracle. 18/18 incl fib, factorial loop, multi-arity, variadic, higher-order,
#() shorthand, the mandelbrot kernel. emit-test 331/331 (emit.janet path
untouched), conformance 355x3. jolt-hg7z.
