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

- one exception: it will still contain any token that will not be
