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

- - 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

- (from LALR or IELR) and default reductions corrupt the expected
