tokens not introducing keyword rules in lexer?

[parrt]

the lexer wouldn't match correctly and would cast them all as id tokens

    tokens { TRUE='true'; FALSE='false'; TYPE_BOOL='boolean'; TYPE_VOID='void'; TYPE_INT='int';
             TYPE_FLOAT='float'; TYPE_CHAR='char';}

    primitiveType
      returns [CymbolProperties props]
      @init{$primitiveType.props = new CymbolProperties();}
      : 'float'
      | 'int'
      | 'char'
      | 'boolean
      | 'void'
      ;

Closing since the tokens{} block can no longer be used in this manner.
