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

+

+ 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
