     - 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 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.
