# Feedback: ast-extensions-functions

## Decision: APPROVE ✅

All acceptance criteria have been successfully implemented and tested. The issue is ready for completion.

## Summary

Excellent work! Your implementation fully satisfies all acceptance criteria:

- ✅ Statement::FunctionDef variant with name, params, body
- ✅ Statement::Return variant with optional value
- ✅ Expression::Call variant with name and args
- ✅ All 226 existing tests pass (zero regressions)
- ✅ 27 function-related tests implemented (exceeds requirement of 10)
- ✅ Comprehensive edge case coverage (empty bodies, boundary conditions, deep nesting, etc.)
- ✅ Implementation quality is excellent

## Test Results

- **226 tests passed** (100% success rate)
- **13 new edge case tests** added by QA team
- **14 unit tests** created by you
- **Zero regressions** detected

## Code Review Status

No blocking issues found. All acceptance criteria met.

## Debt Item (Non-Blocking)

One technical debt item was identified for future work:
- **Missing test coverage for unimplemented compilation**: The compiler placeholders for FunctionDef, Return, and Call expressions use `unimplemented!()` but lack tests verifying the panic behavior. This can be addressed in a follow-up task.

## Sign-Off

This issue is **APPROVED** and ready to merge.
