Created TokenKind enum with all token types - Created GenericToken class backed by TokenKind to replace single-purpose token classes - Added abstract getKind(): TokenKind to BaseToken - Made getType() concrete in BaseToken, deriving TokenType from getKind() - Removed isOfType() method (unused) - Removed kindToType() from TokenFactory (duplicated in BaseToken::getType()) - Updated canBeIgnored() to use getKind() directly - Updated ExpressionFactory to use TokenKind matching instead of instanceof - Removed 27 old token class files - Updated all tests accordingly All 278 tests pass. --- src/AST/ArrayNode.php | 2 +- src/Expression/ExpressionFactory.php | 24 ++-- src/Parser/Parser.php | 125 +++++++----------- src/TokenStream/Token/BaseToken.php | 40 +++++- src/TokenStream/Token/GenericToken.php | 30 +++++ src/TokenStream/Token/TokenAnd.php | 18 --- src/TokenStream/Token/TokenArray.php | 4 +- src/TokenStream/Token/TokenBool.php | 5 -
