+ syntactic action. Thus, if the lookahead eventually proves
+ syntactically unacceptable (possibly in a later context reached via a

+ further semantic actions would be erroneous because they would be
+ determined by a syntactically unacceptable token.
+
+ YY_LAC_ESTABLISH should be invoked when a reduction is about to be
+ performed in an inconsistent state (which, for the purposes of LAC,
+ includes consistent states that don't know they're consistent because
+ their default reductions have been disabled). Iff there is a
+ lookahead token, it should also be invoked before reporting a syntax
+ error. This latter case is for the sake of the debugging output.
+
+ For parse.lac=full, the implementation of YY_LAC_ESTABLISH is as
+ follows. If no initial context is currently established for the
+ current lookahead, then check if that lookahead can eventually be
+ shifted if syntactic actions continue from the current context.

+ - 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.
+ In the first two cases, it might appear that the current syntax
+ error should have been detected in the previous state when yy_lac
+ 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 current lookahead.
