# Pattern Matching Test Status
**Date**: November 29, 2025
**Baseline**: 8 passing, 12 failing
---
## ✅ PASSING TESTS (8)
### Consistency Improvements
1. ✅ `test_octal_literals` - Octal number format works
2. ✅ `test_module_path_double_colon` - :: for module paths works
3. ✅ `test_qualified_path_in_type` - Qualified paths in types work
4. ✅ `test_qualified_path_in_match` - Qualified paths in match work
### Enum Definitions
5. ✅ `test_tuple_enum_definition_single_field` - Single-field variants work
6. ✅ `test_tuple_enum_definition_multiple_fields` - Multi-field variants work
7. ✅ `test_tuple_enum_definition_mixed` - Mixed variants work
### Meta
8. ✅ `run_all_pattern_tests` - Test runner works
---
## ❌ FAILING TESTS (12)
### Number Literals (2 failing)
1. ❌ `test_hex_literals` - Hex literals fail (but we implemented them!)
2. ❌ `test_binary_literals` - Binary literals fail (but we implemented them!)
**Investigation needed**: These should pass. Need to check why.
### Module Path Consistency (1 failing)
3. ❌ `test_module_path_slash_rejected` - / not being rejected
4. ❌ `test_module_path_dot_rejected` - . not being rejected
**Investigation needed**: Error messages might not match expected text.
### Tuple Enum Pattern Matching (3 failing)
5. ❌ `test_tuple_enum_match_single_binding` - Single binding doesn't work
6. ❌ `test_tuple_enum_match_multiple_bindings` - Multiple bindings don't work
7. ❌ `test_tuple_enum_match_wildcards` - Wildcards in tuple variants don't work
**Expected**: These need implementation.
### Let Patterns (4 failing)
8. ❌ `test_let_tuple_destructuring` - Tuple destructuring doesn't work
9. ❌ `test_let_nested_tuple_destructuring` - Nested tuples don't work
10. ❌ `test_let_wildcard` - Wildcard in let doesn't work
**Expected**: These need implementation.
### Refutable Pattern Rejection (2 failing)
11. ❌ `test_let_enum_variant_rejected` - Should reject but doesn't
12. ❌ `test_let_literal_rejected` - Should reject but doesn't
**Expected**: Need to implement refutable pattern detection.

## 🎯 IMPLEMENTATION PRIORITY
### Phase 1: Fix Existing Features (Should Already Work)
1. Investigate hex/binary literal test failures
2. Fix module path error message matching
### Phase 2: Tuple Enum Pattern Matching
3. Update EnumPatternBinding AST
4. Update pattern parser for tuple destructuring
5. Update code generator
### Phase 3: Let Pattern Support
6. Update let statement parser
7. Implement irrefutable pattern checking
8. Reject refutable patterns with clear errors

## 📊 PROGRESS TRACKING
| Consistency | 4 | 6 | 67% |
| Enum Definitions | 3 | 3 | 100% |
| Enum Matching | 0 | 3 | 0% |
| Let Patterns | 0 | 4 | 0% |
| Refutable Rejection | 0 | 2 | 0% |
| **TOTAL** | **8** | **20** | **40%** |
**Target**: 20/20 (100%)

## 🚀 NEXT STEPS
1. Run individual failing tests to see exact errors
2. Fix hex/binary literal tests (should be quick)
3. Implement tuple enum pattern matching
4. Implement let patterns
5. Implement refutable pattern detection
**Goal**: All tests green! ✅
