🚀 feat: Multiple improvements for Nyash parser and LLVM backend Parser improvements: - Added expression statement fallback in parse_statement() for flexible syntax - Fixed ternary operator to use PeekExpr instead of If AST (better lowering) - Added peek_token() check to avoid ?/?: operator conflicts LLVM Python improvements: - Added optional ESC_JSON_FIX environment flag for string concatenation - Improved PHI generation with better default handling - Enhanced substring tracking for esc_json pattern Documentation updates: - Updated language guide with peek expression examples - Added box theory diagrams to Phase 15 planning - Clarified peek vs when syntax differences These changes enable cleaner parser implementation for self-hosting, especially for handling digit conversion with peek expressions instead of 19-line if-else chains. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> 2025-09-14 19:16:32 +09:00			`static box Main {`

parser(match): introduce expression (replaces syntax); keep AST PeekExpr lowering - Tokenizer: add MATCH keyword; remove PEEK - Parser: parse (MVP: literal patterns, block/expr arms); build PeekExpr AST for existing lowering - Tests/Smokes: update peek samples to match; skip one return-value case pending richer arm parsing Notes: MIR unchanged; existing PeekExpr lowerers continue to work. 2025-09-19 07:58:01 +09:00			`local dv = match d {`
