  /* There are many possibilities here to consider:
     - If this state is a consistent state with a default action, then
       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.
