# Changelog

All notable changes to this package will be documented in this file.

## [0.6.0] - 2026-03-10

### Added
- **Rust-like match patterns**: `Tuple(Vec<Pattern>)`, `IntLiteral(i64)`, `BoolLiteral(bool)` pattern variants
- Parse tuple patterns: `(a, b) ->`
- Parse boolean literal patterns: `true ->` / `false ->`
- Parse integer literal patterns: `42 ->`
- Parse nested constructors: `Some(Ok(x)) ->`
- Wildcard `_` now correctly parsed as `Pattern::Wildcard` (was `Ident("_")`)
- `can_be_pattern()` recognizes `LParen`, `True`, `False` as pattern starts
- 5 new parser tests for match patterns (tuple, int, bool, nested, mixed arms)
- 12 resilient parsing tests covering all Declaration and Expression variants

### Test Coverage
- **49 tests** (was 32 in v0.5.0)

## [0.5.0] - 2026-03-09
