1089 - The only way there can be no lookahead present (in yychar) is if

1091 detecting the absence of a lookahead is sufficient to determine
1092 that there is no unexpected or expected token to report. In that

1094 - Don't assume there isn't a lookahead just because this state is a
1095 consistent state with a default action. There might have been a
1096 previous inconsistent state, consistent state with a non-default
1097 action, or user semantic action that manipulated yychar.
1098 - Of course, the expected token list depends on states to have
1099 correct lookahead information, and it depends on the parser not
1100 to perform extra reductions after fetching a lookahead from the
1101 scanner and before detecting a syntax error. Thus, state merging
1102 (from LALR or IELR) and default reductions corrupt the expected
