## Summary Documented the "init block vs fields-at-top" design discussion as a valuable example of AI-human collaboration in language design. ## Changes ### Paper G (AI Collaboration) - Added field-declaration-design.md documenting the entire discussion flow - Showcased how complex init block proposal evolved to simple "fields at top" rule - Demonstrates AI's tendency toward complexity vs human intuition for simplicity ### Paper H (AI Practical Patterns) - Added Pattern #17: "Gradual Refinement Pattern" (段階的洗練型) - Documents the process: Complex AI proposal → Detailed analysis → Human insight → Convergence - Field declaration design as a typical example ### Paper K (Explosive Incidents) - Added Incident #046: "init block vs fields-at-top incident" - Updated total count to 46 incidents - Shows how a single human comment redirected entire design approach ## Design Decision After analysis, decided that BoxIndex should remain a compiler-internal structure, not a core Box: - Core Boxes: User-instantiable runtime values (String, Integer, Array, Map) - Compiler internals: BoxIndex for name resolution (compile-time only) - Clear separation of concerns between language features and compiler tools ## Philosophy This discussion exemplifies key principles: - The best design needs no explanation - Constraints provide clarity, not limitation - "Everything is Box" doesn't mean "compiler internals are Boxes" - AI tends toward theoretical completeness; humans toward practical simplicity 🐱 Sometimes the simplest answer is right in front of us\!
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 (peek, ternary, sugar):
- 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
- Peek Expression Design/Usage: covered in the Language Reference and Phase 12.7 specs above
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 —
usingsyntax, runner resolution, and style guidance.
Grammar (EBNF)
- See: reference/language/EBNF.md — Stage‑2 grammar specification used by parser implementations.
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 (peek, ternary, null‑safe).
