1141+ detecting the absence of a lookahead is sufficient to determine
1142+ that there is no unexpected or expected token to report. In that

1144+ - Don't assume there isn't a lookahead just because this state is a

1146+ previous inconsistent state, consistent state with a non-default
1147+ action, or user semantic action that manipulated yychar.
1148+ - Of course, the expected token list depends on states to have
1149+ correct lookahead information, and it depends on the parser not
1150+ to perform extra reductions after fetching a lookahead from the
1151+ scanner and before detecting a syntax error. Thus, state merging
1152+ (from LALR or IELR) and default reductions corrupt the expected
1153+ token list. However, the list is correct for canonical LR with
1154+ one exception: it will still contain any token that will not be
