# Feedback: value-copy-trait

## Decision: ✅ APPROVE

All acceptance criteria met and verified:

1. **Copy trait added** ✓ - Value enum now derives Copy in addition to Clone
2. **as_integer() documentation** ✓ - Panic behavior documented with detailed error message
3. **All tests pass** ✓ - 344/344 tests passed including all existing tests (no modifications required)
4. **No compilation errors/warnings** ✓ - No new issues introduced (pre-existing warnings are unrelated)

## Quality Assessment

**Test Coverage**: Excellent. 6 new tests added specifically for:
- Copy trait semantics validation (AC1)
- as_integer() panic behavior on None (AC2)
- Comprehensive edge case coverage for None handling in binary/unary operations

**Code Quality**: Implementation is minimal, focused, and backward compatible. Copy trait is valid (Integer(i64) and None are both Copy-compatible) and provides real performance benefits (11+ eliminated .clone() calls in VM register operations).

## Summary

This issue is complete and ready to merge. All requirements have been satisfied and comprehensively tested.
