- Created token-to-string mapping array parallel to Token enum in token.c - Implemented TokenStream with lookahead buffering for proper tokenization - Implemented tokenstream_open/close/next functions with support for: - Keywords (module, import, void) - Symbols (parentheses, brackets, comma, semicolon) - Identifiers (alphanumeric starting with letter or underscore) - Comment skipping (// style) - Whitespace handling - Added token_to_string function to token.h for token inspection - Created comprehensive test suite (15 tests) covering all token types and edge cases - All tests pass.
