         tokens because there are none.
       - 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
         accepted due to an error action in a later state.
