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

       this state is a consistent state with a default action.  Thus,

       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

       token list.  However, the list is correct for canonical LR with

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