-       that there is no unexpected or expected token to report.  In that

-     - 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.
