- Created KeywordMap structure with keyword-to-token mapping at top of token.c
- Added lookup_keyword() function to check if identifier is a keyword
- Replaced 3 strcmp calls (lines 99-101) with single lookup_keyword() call
- Removed token_to_string() function and its tests (3 tests removed)
- Single easy-to-read and modify keyword map serves both documentation and implementation
- Added new keywords by editing the keywords[] array at top of token.c
All 12 tests passing (removed token_to_string tests which are now unnecessary).
