Selfhosting Dev d9f26d4549 feat: nyash.toml SSOT + using AST統合完了（12時間の戦い） 
- nyash.tomlを唯一の真実（SSOT）として依存管理確立
- dev/ci/prodプロファイルによる段階的厳格化実装
- AST結合で宣言/式の曖昧性を根本解決
- Fail-Fast原則をCLAUDE.md/AGENTS.mdに明文化
- VM fallbackでもASTベース using有効化（NYASH_USING_AST=1）
- 静的メソッドの is_static=true 修正で解決安定化
- STATICブレークハック既定OFF化で堅牢性向上

🎉 usingシステム完全体への道筋確立！JSONライブラリ・Nyash VM開発が可能に

freeze: macro platform complete; default ON with profiles; env consolidation; docs + smokes\n\n- Profiles: --profile {lite|dev|ci|strict} (dev-like default for macros)\n- Macro paths: prefer NYASH_MACRO_PATHS (legacy envs deprecated with warnings)\n- Selfhost pre-expand: auto mode, PyVM-only, add smokes (array/map)\n- Docs: user-macros updated; new macro-profiles guide; AGENTS freeze note; CURRENT_TASK freeze\n- Compat: non-breaking; legacy envs print deprecation notices\n

Nyash Language Reference – Index

This is the entry point for Nyash language documentation.

  • Full Language Reference (2025): reference/language/LANGUAGE_REFERENCE_2025.md
  • Syntax Cheat Sheet: quick-reference/syntax-cheatsheet.md
  • Phase 12.7 Grammar Specs (ternary, sugar; peek → match に統合):
    • Overview: development/roadmap/phases/phase-12.7/grammar-specs/README.md
    • Token/Grammar: development/roadmap/phases/phase-12.7/ancp-specs/ANCP-Token-Specification-v1.md
  • Sugar Transformations (?., ??, |> and friends): parser/sugar.rs (source) and tools/nyfmt/NYFMT_POC_ROADMAP.md
  • Match Expression (pattern matching): see the Language Reference and EBNF (peek was replaced by match)

Statement separation and semicolons

  • See: reference/language/statements.md — newline as primary separator; semicolons optional for multiple statements on one line; minimal ASI rules.

Imports and namespaces

  • See: reference/language/using.md — using syntax, runner resolution, and style guidance.

Grammar (EBNF)

  • See: reference/language/EBNF.md — Stage‑2 grammar specification used by parser implementations.
  • Unified Members (stored/computed/once/birth_once): see reference/language/EBNF.md “Box Members (Phase 15)” and the Language Reference section. Default ON (disable with NYASH_ENABLE_UNIFIED_MEMBERS=0).

Member exceptions and handlers (Stage‑3)

  • Postfix catch/cleanup may be attached to computed/once/birth_once/method blocks when Stage‑3 is enabled. Stored members (plain name: Type [= expr]) do not support handlers.

Related implementation notes

  • Tokenizer: src/tokenizer.rs
  • Parser (expressions/statements): src/parser/expressions.rs, src/parser/statements.rs
  • MIR Lowering (expressions): src/mir/builder/exprs.rs and friends

Navigation tips

  • The “reference/language/LANGUAGE_REFERENCE_2025.md” is the canonical long‑form reference; use the Cheat Sheet for quick syntax lookup.
  • Phase 12.7 files capture the finalized sugar and new constructs (match (replaces peek), ternary, null‑safe).
