1062        for details.  YYERROR is fine as it does not invoke this
1063        function.
1064      - If this state is a consistent state with a default action, then
1065        the only way this function was invoked is if the default action
1066        is an error action.  In that case, don't check for expected
1067        tokens because there are none.
1068      - The only way there can be no lookahead present (in yychar) is if
1069        this state is a consistent state with a default action.  Thus,
1070        detecting the absence of a lookahead is sufficient to determine
1071        that there is no unexpected or expected token to report.  In that
1072        case, just report a simple "syntax error".
1073      - Don't assume there isn't a lookahead just because this state is a
1074        consistent state with a default action.  There might have been a
1075        previous inconsistent state, consistent state with a non-default
1076        action, or user semantic action that manipulated yychar.
1077      - Of course, the expected token list depends on states to have
1078        correct lookahead information, and it depends on the parser not
1079        to perform extra reductions after fetching a lookahead from the
1080        scanner and before detecting a syntax error.  Thus, state merging
1081        (from LALR or IELR) and default reductions corrupt the expected
1082        token list.  However, the list is correct for canonical LR with
1083        one exception: it will still contain any token that will not be
1084        accepted due to an error action in a later state.
