1217 - Assume YYFAIL is not used. It's too flawed to consider. See

1222 the only way this function was invoked is if the default action

1226 this state is a consistent state with a default action. Thus,
1227 detecting the absence of a lookahead is sufficient to determine
1228 that there is no unexpected or expected token to report. In that
