1047 detecting the absence of a lookahead is sufficient to determine
1048 that there is no unexpected or expected token to report. In that
1049 case, just report a simple "syntax error".
1050 - Don't assume there isn't a lookahead just because this state is a
1051 consistent state with a default action. There might have been a
1052 previous inconsistent state, consistent state with a non-default
1053 action, or user semantic action that manipulated yychar.
1054 - Of course, the expected token list depends on states to have
1055 correct lookahead information, and it depends on the parser not
1056 to perform extra reductions after fetching a lookahead from the
1057 scanner and before detecting a syntax error. Thus, state merging
1058 (from LALR or IELR) and default reductions corrupt the expected
