 |        for details.  YYERROR is fine as it does not invoke this | 
 |        function. | 
 |      - If this state is a consistent state with a default action, then | 
 |        the only way this function was invoked is if the default action | 
 |        is an error action.  In that case, don't check for expected | 
 |        tokens because there are none. | 
 |      - The only way there can be no lookahead present (in yychar) is if | 
 |        this state is a consistent state with a default action.  Thus, | 
 |        detecting the absence of a lookahead is sufficient to determine | 
 |        that there is no unexpected or expected token to report.  In that | 
 |        case, just report a simple "syntax error". | 
 |      - Don't assume there isn't a lookahead just because this state is a | 
 |        consistent state with a default action.  There might have been a | 
 |        previous inconsistent state, consistent state with a non-default | 
 |        action, or user semantic action that manipulated yychar. | 
 |      - Of course, the expected token list depends on states to have | 
 |        correct lookahead information, and it depends on the parser not | 
 |        to perform extra reductions after fetching a lookahead from the | 
 |        scanner and before detecting a syntax error.  Thus, state merging | 
 |        (from LALR or IELR) and default reductions corrupt the expected | 
 |        token list.  However, the list is correct for canonical LR with | 
 |        one exception: it will still contain any token that will not be | 
 |        accepted due to an error action in a later state. |
