1985 tokens because there are none.
1986 - The only way there can be no lookahead present (in yyla) is
1987 if this state is a consistent state with a default action.
1988 Thus, detecting the absence of a lookahead is sufficient to
1989 determine that there is no unexpected or expected token to
1990 report. In that case, just report a simple "syntax error".
1991 - Don't assume there isn't a lookahead just because this state is
1992 a consistent state with a default action. There might have
1993 been a previous inconsistent state, consistent state with a
1994 non-default action, or user semantic action that manipulated
1995 yyla. (However, yyla is currently not documented for users.)
1996 - Of course, the expected token list depends on states to have
1997 correct lookahead information, and it depends on the parser not
1998 to perform extra reductions after fetching a lookahead from the
1999 scanner and before detecting a syntax error. Thus, state merging
2000 (from LALR or IELR) and default reductions corrupt the expected
2001 token list. However, the list is correct for canonical LR with
2002 one exception: it will still contain any token that will not be
2003 accepted due to an error action in a later state.
