* Reader: #() params survive syntax-quote (auto-gensym names) #(...) named its synthesized params with bare gensyms, so a #() written inside a syntax-quote had its params qualified to the current ns by sq-symbol — and a qualified symbol isn't a valid fn param. hiccup's compiler emits `(let [sb# ..] (iterate! #(.append sb# %) ..)), which broke with "Unable to resolve symbol: ns/_NNNN". Name the params with a trailing # (auto-gensym suffix, like Clojure's p1__N#) so syntax-quote maps them consistently and leaves them unqualified. Harmless outside a backtick (just a regular symbol name). * interop: String/valueOf static + String is a CharSequence Two interop gaps surfaced bringing up hiccup and malli: - String/valueOf(Object): hiccup's compiler stringifies attribute values with (String/valueOf (or arg "")). Added the static — "null" for nil, else core-str. - (instance? CharSequence s) returned false for a string; String implements CharSequence, and malli's :re validator gates on it before matching, so :re schemas always failed. instance-check now answers true for strings. --------- Co-authored-by: Yogthos <yogthos@gmail.com> |

The Clojure Language Specification (Draft)
A normative, implementation-independent specification of the Clojure
language, developed alongside jolt's self-hosted compiler and validated by
its executable conformance suites. Why: Clojure has no spec — every
alternative implementation re-derives semantics from the reference
implementation and folklore. See the RFC for motivation, scope, evidence
sources, and process: ../rfc/0001-language-specification.md.

Current numbers (2026-06-10)
Of the 694 clojure.core vars in the ClojureDocs inventory:
- 380 implemented in jolt and exercised by the behavioral suites
- 154 implemented but not directly tested — each gets a test with its spec entry
- 35 portable but missing from jolt (
parse-long/parse-double/parse-boolean,update-keys/update-vals,macroexpand,time,partitionv/partitionv-all/splitv-at,with-redefs,with-open, reader fns, ns-introspection stragglers, …) — tracked as implementation gaps - 22 resolvable in code but invisible to ns introspection
(
resolve/ns-publicscan't see seed-fallback names likecompare,gensym,type) — a conformance finding in its own right - the rest classified host/JVM/concurrency (see dashboard)
How this connects to the test suites
test/integration/conformance-test.janet— 302 assertions, each run through three independent execution paths (interpreter, bootstrap compiler, self-hosted compiler) that must agree. Spec entries cite these.test/spec/*.janet— ~1,500 behavioral cases organized by topic.vendor/clojure-test-suite— the cross-dialect suite (≥4081 assertions passing); dialect splits there are classification evidence.- jank's per-construct corpus (
~/src/jank/compiler+runtime/test/jank) is the granularity model for §2/§3 conformance.
The invariant: every numbered normative statement names its conformance test, or is marked UNVERIFIED. The spec cannot drift from the implementations that check it.
