Closes the last two non-host-interop prelude emit gaps. letfn now analyzes to a :let node flagged :letrec — the binding fns are bound into the env together before any spec is analyzed, so siblings and self resolve. The Chez back end lowers it to letrec*; the Janet back end punts it at emit (its sequential let* can't express the mutual recursion — same interpreter fallback as before, just decided at emit-ir instead of analyze). (def x) with no init (declare) analyzes to a :def with :no-init instead of punting. Chez reserves the var cell via declare-var! (which doesn't clobber an existing root — (do (def x 7) (def x) x) => 7); the Janet back end still punts to the interpreter, which interns a genuinely-unbound var. fallback-zero-test now checks emit-ir too, not just analyze-form, so the real compile-vs-interpret decision is what it asserts (letfn/def-no-init analyze but the Janet back end punts them). letfn stays in must-punt with an updated note. Prelude emit reach 342 -> 348/355 (40-lazy now 13/13); Chez subset 664 -> 672, 0 divergences; emit-test 110 -> 117. Full gate green. |
