 831 |        detecting the absence of a lookahead is sufficient to determine
 832 |        that there is no unexpected or expected token to report.  In that
 833 |        case, just report a simple "syntax error".
 834 |      - Don't assume there isn't a lookahead just because this state is a
 835 |        consistent state with a default action.  There might have been a
 836 |        previous inconsistent state, consistent state with a non-default
 837 |        action, or user semantic action that manipulated yychar.
 838 |      - Of course, the expected token list depends on states to have
 839 |        correct lookahead information, and it depends on the parser not
 840 |        to perform extra reductions after fetching a lookahead from the
 841 |        scanner and before detecting a syntax error.  Thus, state merging
 842 |        (from LALR or IELR) and default reductions corrupt the expected
 843 |        token list.  However, the list is correct for canonical LR with
 844 |        one exception: it will still contain any token that will not be
