+ parser initially examines that lookahead in order to select a
+ 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.
+
+ 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.
