syntactic action. Thus, if the lookahead eventually proves
syntactically unacceptable (possibly in a later context reached via a
series of reductions), the initial context can be used to determine
the exact set of tokens that would be syntactically acceptable in the
lookahead's place. Moreover, it is the context after which any
further semantic actions would be erroneous because they would be
determined by a syntactically unacceptable token.

includes consistent states that don't know they're consistent because
their default reductions have been disabled).

occurs when the lookahead is syntactically erroneous for the

the parser stacks to try to find a new initial context in which the

- 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.)
In the first two cases, it might appear that the current syntax
error should have been detected in the previous state when
yy_lac_check was invoked. However, at that time, there might
have been a different syntax error that discarded a different
initial context during error recovery, leaving behind the
