- (class x) returns per-type JVM class names (Long/Double/Ratio/Character/Atom),
not a blanket java.lang.Number.
- register fully-qualified class tokens (java.lang.Long, clojure.lang.Keyword,
clojure.lang.Atom, ...) that self-evaluate to their name, so (= (class 1)
java.lang.Long) and (instance? clojure.lang.Atom x) resolve.
- instance? recognizes Long/Double/Ratio/Character/Symbol/Atom/IFn built-ins.
Closes class number/string/keyword/name, instance? Atom, atom?. Corpus 2699->2705.
Rephrase comments that pointed at deleted Janet files (emit.janet, the seed
sources, 'the Janet back end punts ...') to present-tense descriptions of the
Chez behavior. Comment/docstring-only; the self-host fixpoint is unchanged
(comments don't affect the compiled seed).
Delete five files that were Janet-host shims with no Chez path: clojure.java.io
(provided natively by host/chez/io.ss), and jolt.{nrepl,png,interop,shell}
(the janet.* bridge, os/shell, janet.net — none exist on Chez).
jolt-cf1q.6
Bare class names (String, Keyword, File...) evaluate to their JVM
canonical-name string, the same value (class x) returns, so
(= String (class "x")) holds and (defmethod m String ...) keys match a
(class ...) dispatch. New host/chez/host-class.ss ports
eval_resolve.janet's class-canonical-names + core_refs.janet's core-class
(scalar arms; collections/seqs are host-taxonomy-dependent and not class-
compared in the corpus).
The analyzer already resolves these names to clojure.core vars (the seed
ctx interns them via setup-class-ctors), so the back end emits
(var-deref "clojure.core" "String") and a runtime def-var! is all that's
needed -- no analyzer change, Janet path untouched. The class native MUST
land together with token resolution: alone it turns the bare-token corpus
cases (562/564) into divergences (this bit last session).
Parity 2154 -> 2163 (cases 560/562/563/564/2500-2503), 0 new divergences.
New test/chez/_class.janet 19/19.
