Route syntax-quote, set!, var, ., new to interpreter
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.

Key design decision: **compile-and-eval emits Janet DATA STRUCTURES, not source strings**, because Janet's `eval` doesn't see `use`-imported symbols. `core-fn-values` table resolves Janet names to actual function values at compile time.

## Compiler Development
|
||||
|
||||
### Adding a new op to the compiler
|
||||
|
||||
1. Add match arm in `analyze-form` — maps Clojure form → AST node
|
||||
2. Add `emit-*-str` for source-to-source path, then arm in `emit-ast` dispatch
|
||||
3. Add `emit-*-expr` for data-structure path, then arm in `emit-expr` dispatch
|
||||
4. Add tests
|
||||
|
||||
### Emitter patterns
|
||||
|
||||
**String emitter**: `(buffer/push buf "...")` → source text
|
||||
**Data-structure emitter**: `['keyword val1 val2]` → eval-able tuples
|
||||
|
||||
### Janet eval gotchas
|
||||
|
||||
- Bare tuples are function calls — always use `['tuple ...]` or `(tuple ...)`
|
||||
- `eval` scope: symbols from `(use ...)` not available — embed function VALUES
|
||||
- Janet `try`: `(try body ([err] handler))` — not `(catch sym handler)`
|
||||
- Core `-` maps to `core-sub` (NOT `core--`)
|
||||
|
||||
### Loop compilation
|
||||
|
||||
`(loop* [x 0] body-with-recur)` → `(do (var name nil) (set name (fn [x] body)) (name 0))`
|
||||
Recur rewrites to `(loop-name arg...)` via `:jolt/current-loop` binding.
|
||||
|
||||
### Quote: use `raw-form->janet` converter, never re-analyze
|
||||
|
||||
### Macro expansion: pass ctx to `analyze-form`, check `resolve-macro`, expand + re-analyze
|
