Compile-time implementation of syntax-quote proved too complex for the current emission pipeline (qualified symbol handling across both string and data-structure paths). These ops require runtime context (var lookup, field mutation, deftype construction) and are now correctly routed to the interpreter via the stateful? check in eval-string. Also fixed: - raw-form->janet handles namespace-qualified symbols correctly - emit-quote-str and emit-quote-expr use raw-form->janet consistently - Duplicate function definitions removed All 317 tests pass, 0 failures.

Janet's `eval` runs in Janet's default environment and does NOT have access to symbols imported via `(use ...)` in the calling file. `(eval '(core-inc 1))` fails with "unknown symbol core-inc" even when the file does `(use ./core)`. FIX: emit Janet data structures where function VALUES are embedded directly (e.g. `[core-inc 1]`) rather than source strings `"(core-inc 1)"`. The `core-fn-values` table resolves Janet symbol names to actual function values at compile time.

Jolt Compiler Architecture (Phases 1-6, dfa9874→1de109f): Two-phase — analyze-form (Clojure form → annotated AST) → emit-ast (→ Janet source string) or emit-expr (→ Janet data structures for eval). analyze-form takes [form bindings &opt ctx]; ctx needed for macro expansion. Symbol classification: bindings first (:local), then core-renames (:core-symbol), then plain (:symbol). Two emitter paths: string (compile-form) and data structures (compile-ast). Core fn values resolved via core-fn-values table. compile-and-eval takes [form ctx]; pass nil for no macro ctx.

Key naming/facts:
|
|
- Clojure - → core-sub (NOT core--)
|
|
- core-nth did not exist — had to add both the function and core-bindings entry
|
|
- Missing from core-renames early: fn?, list, name, subs
|
|
- Bare tuples in Janet eval → treated as function calls. Always emit (tuple ...) or ['tuple ...]
|
|
- make-symbol: / at position 0 means unqualified symbol (was parsing empty ns)
|
|
- raw-form->janet converter for quote: don't re-analyze quoted forms, pass through verbatim
|
|
- emit-try-expr: Janet format is (try body ([err] handler)) not (try body (catch sym handler))
|
|
- Loop compilation: (do (var _loop_N nil) (set _loop_N (fn [params] body)) (_loop_N init-vals...))
|
|
- Recur compilation: rewrites to (loop-name arg1 arg2...) via :loop-name in AST
|
|
|
|
eval-string dispatch: When :compile? true, stateful forms (defmacro, ns, deftype, defmulti, defmethod, require, in-ns) use interpreter. All others (def, macros like defn) go through compile-and-eval. Macros expanded at analyze time via resolve-macro.
|
|
|
|
Remaining: syntax-quote, set! compiler support. deftype/defmulti/defmethod routed to interpreter.

Phase 6: 47 comprehensive compile-mode tests in test/phase6-final.janet. Collections, math, predicates, comparison, seq ops (map/filter/reduce/take/drop), special forms (let/if/loop/try/quote), macros (defn/when/and/or/fn/if-let), complex nesting. 58 assertions. All 317 tests pass, 0 failures. Remaining: syntax-quote, set! compiler support. deftype, defmulti/defmethod routed to interpreter (stateful).
