Hakorune Compiler — Layout and Responsibilities

Structure (target)

• emit/
  • mir_emitter_box.hako — high-level MIR emitter entry
  • common/ — shared emit helpers (mir_emit/json_emit/call_emit/header_emit/newbox_emit)
• parser/ — lexer/parser (to be moved from apps/* in later steps)
• builder/, ssa/, rewrite/, pipeline_v2/ — existing compiler stages (move gradually)

Policy

• Compiler lives under lang/src/compiler/.
• VM engines live under lang/src/vm/engines/ (Hakorune/Mini), with shared helpers in vm/boxes/.
• Keep imports across these boundaries minimal and documented.

Grammar Notes (parser parity)

• Semicolons are accepted as optional statement separators (default ON).
  • Both newline and ; delimit statements; trailing }; is allowed.
  • Consecutive ;; are treated as empty statements (no-op).
  • Env toggle (opt-out): set NYASH_PARSER_ALLOW_SEMICOLON=0|false|off to disable.
