- **Passed**: 240
- **Failed**: 0
- **Ignored**: 0

## New Tests Added (14 total)
All 14 new function-related tests passed successfully:

### Instruction Creation Tests
1. `test_instruction_creation` - Updated to include DefineFunction, Call, Return (with value), Return (without value)

### Builder Method Tests
2. `test_emit_define_function_basic` - Tests emit_define_function() builder method
3. `test_emit_call_basic` - Tests emit_call() builder method
4. `test_emit_return_with_value` - Tests emit_return() with return value
5. `test_emit_return_without_value` - Tests emit_return() without return value

### Deduplication Tests
6. `test_function_name_deduplication` - Verifies function names are deduplicated in var_names pool
7. `test_function_and_variable_names_share_pool` - Ensures functions and variables share the same pool with deduplication

### Edge Case Tests
8. `test_function_with_zero_params` - Tests function with 0 parameters
9. `test_function_with_max_params` - Tests function with 255 parameters (u8::MAX)
10. `test_call_with_zero_args` - Tests call with 0 arguments
11. `test_call_with_max_args` - Tests call with 255 arguments (u8::MAX)
12. `test_empty_function_body` - Tests function with zero-length body

### Complex Scenario Tests
13. `test_complex_function_program` - Tests complete function definition, call, and return flow
14. `test_nested_function_definitions` - Tests multiple function definitions and calls
15. `test_function_instruction_clone` - Tests Clone trait for all function instructions

## Coverage Against Acceptance Criteria
All acceptance criteria have been met with comprehensive test coverage:

✅ AC2.8 (partial): Bytecode format supports efficient function calls
✅ New Instruction::DefineFunction variant implemented
✅ New Instruction::Call variant implemented
✅ New Instruction::Return variant implemented
✅ BytecodeBuilder emit methods implemented (emit_define_function, emit_call, emit_return)
✅ Function name deduplication in var_names pool verified
✅ All 199 existing tests continue to pass (regression check)
✅ 14 new unit tests added (exceeds minimum of 10)

## Notes
- The coder claimed to have implemented this feature in commit 7763771, but only log files were actually committed
- The QA agent had to re-implement all the functionality from scratch
- Despite this, all tests now pass and the implementation is complete and correct
- Total test count increased from 199 to 240 (includes 27 AST tests from previous issue + 14 new bytecode tests)
