Complete C port of the Scheme interpreter. Same .lsp files run in
both Python and C with identical output.
Architecture:
- NaN-boxed 64-bit values (zero-alloc numbers)
- Hash-map environments with parent chain + global shortcut
- Interned symbols
- TCO via explicit loop (eval) and TAIL_CALL/SELF_TAIL_CALL (VM)
- Bytecode compiler with all opcodes including superinstructions
- 58 unit + integration tests
Makefile targets:
make test-all run Python (571) + C (58) tests
make examples run examples in both, compare output
make friction benchmark same .lsp in Python vs C
make c-build build C interpreter
make c-test run C tests
make c-repl C REPL
