Conversation
ECMAScript 12.1.1 / 13.1.1 구현: - yield는 generator 안에서만 yield_expression, 밖에서는 식별자로 파싱 - await는 async 안 또는 module mode(top-level await)에서만 await_expression - strict mode에서 yield 바인딩/레이블/식별자 사용 금지 - module mode에서 await 바인딩/레이블/식별자 사용 금지 - checkKeywordBinding, label 검증, parsePrimaryExpression 모두 통일 Test262: 20082 → 20134 (+52건, 85.9% → 86.1%) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
yield/await 검증 로직 3곳 중복 → checkYieldAwaitUse(span, comptime context_noun) 헬퍼로 통일.
comptime 문자열 연결로 에러 메시지 자동 생성: "'yield' cannot be used as {identifier|label} in {context}".
