The back end emitted a direct Janet call (f args) for every :var/:local callee,
but Janet calling a pvec-table does get (no integer key -> nil), a keyword does
the wrong thing, etc. — so (let [v [1 2 3]] (v 0)), a keyword/meta-vector in a
binding, all returned nil in compile mode (interpret was fine). Now a direct call
is emitted only when the callee is provably a function: :fn / :host always, and a
:var whose current root is a function; everything else routes through jolt-call,
which dispatches IFn correctly (function fast-path first). User/core fn calls stay
direct, so no hot-path regression — fixpoint stage1==stage2==stage3 holds.
Conformance 218/218 all modes; full suite green. Spec cases added.
Add behavioral spec suites for the collection API (~180 cases). Writing them
surfaced and fixed real bugs:
- (count nil) errored; now 0 (Clojure semantics)
- (repeat x) and (repeatedly f) — the infinite 1-arg arities — were unsupported;
now return lazy infinite seqs
- set equality used deep= (representation-sensitive), so a set of map literals
could differ from an equal set built differently; now value-based (each
element value-equal to some element of the other)
Known limitation filed: phm-typed maps (from hash-map) used as set elements /
map keys hash by identity (map *literals* are structs and work).
jpm test green.
