       the only way this function was invoked is if the default action
       is an error action.  In that case, don't check for expected
       tokens because there are none.
     - The only way there can be no lookahead present (in yyla) 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
       yyla.  (However, yyla is currently not documented for users.)
     - 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.
