Richard Feldman 7d0a269fb7 Implement ? (question mark) operator for error propagation ... The ? operator now desugars expr? to a match expression that unwraps Ok values and early returns Err values: match expr { Ok($q_ok) => $q_ok, Err($q_err) => return Err($q_err), } Implementation details: - Canonicalize the inner expression - Create synthetic identifiers for Ok/Err values ($q_ok, $q_err) - Create applied_tag patterns for Ok and Err - Build match branches with proper scope isolation - Mark synthetic patterns as used to avoid unused variable warnings - Create e_lookup_local, e_tag, and e_return expressions for branch bodies 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>		2025-11-29 20:02:01 -05:00
