All from adapting jank's form/reader tests; each fix verified in interpret +
compile modes and the spec tests now assert the correct behavior.
- jolt-vdo: case now rejects duplicate test constants at expansion (Clojure
compile error), via bootstrap-safe duplicate detection (00-syntax; analyzer.clj
uses case during its own build, so seed-only fns).
- jolt-w2v: loop bindings are now sequential like let — a later init can
reference an earlier binding. Fixed the interpreter loop* (accumulating scope)
and the back end emit-loop (bind initial inits in a sequential Janet let before
entering the recur target).
- jolt-6x1: #() reader computes the fixed arity from the MAX positional (%2 ->
[p1 p2 & rest]); % and %1 unify; unused lower slots get placeholder params.
- jolt-xl0: ^meta on collection literals ({}/[]/#{}) now attaches — read-meta
passes the NORMALIZED metadata map to with-meta (was the raw meta-form).
- jolt-edb: syntax-quote processes ~/~@ inside set literals (new __sqset builder
in core + set branches in syntax-quote* and syntax-quote-lower).
Deferred: jolt-265 (fully-qualify core syms to clojure.core/ in syntax-quote) —
it passes conformance but breaks the standalone uberscript (the ns macro emits
unqualified require/in-ns, which then qualify and break bundled require/alias).
Reverted to bare (functionally resolves); re-opened with the finding.
Gate green incl full jpm build + jpm test: conformance 269x3, suite >=4034/67,
fixpoint, self-host, sci 422/0, uberscript, all unit + spec (forms 55, reader 31).
