1399 We define a context as a snapshot of the parser stacks. We define
1400 the initial context for a lookahead as the context in which the
1401 parser initially examines that lookahead in order to select a
1402 syntactic action. Thus, if the lookahead eventually proves
1403 syntactically unacceptable (possibly in a later context reached via a
1404 series of reductions), the initial context can be used to determine
1405 the exact set of tokens that would be syntactically acceptable in the
1406 lookahead's place. Moreover, it is the context after which any
1407 further semantic actions would be erroneous because they would be
1408 determined by a syntactically unacceptable token.
1409
1410 YY_LAC_ESTABLISH should be invoked when a reduction is about to be
1411 performed in an inconsistent state (which, for the purposes of LAC,
1412 includes consistent states that don't know they're consistent because
1413 their default reductions have been disabled). Iff there is a
1414 lookahead token, it should also be invoked before reporting a syntax
1415 error. This latter case is for the sake of the debugging output.
1416
1417 For parse.lac=full, the implementation of YY_LAC_ESTABLISH is as
1418 follows. If no initial context is currently established for the
1419 current lookahead, then check if that lookahead can eventually be
1420 shifted if syntactic actions continue from the current context.

1708 - The only way there can be no lookahead present (in yychar) is if
1709 this state is a consistent state with a default action. Thus,
1710 detecting the absence of a lookahead is sufficient to determine
