| 1322 | the initial context for a lookahead as the context in which the |
| 1323 | parser initially examines that lookahead in order to select a |
| 1324 | syntactic action. Thus, if the lookahead eventually proves |
| 1325 | syntactically unacceptable (possibly in a later context reached via a |
| 1326 | series of reductions), the initial context can be used to determine |
| 1327 | the exact set of tokens that would be syntactically acceptable in the |
| 1328 | lookahead's place. Moreover, it is the context after which any |
| 1329 | further semantic actions would be erroneous because they would be |
| 1330 | determined by a syntactically unacceptable token. |

| 1333 | performed in an inconsistent state (which, for the purposes of LAC, |
| 1334 | includes consistent states that don't know they're consistent because |
| 1335 | their default reductions have been disabled). Iff there is a |
| 1336 | lookahead token, it should also be invoked before reporting a syntax |
| 1337 | error. This latter case is for the sake of the debugging output. |
| 1338 | |
| 1339 | For parse.lac=full, the implementation of YY_LAC_ESTABLISH is as |
| 1340 | follows. If no initial context is currently established for the |
| 1341 | current lookahead, then check if that lookahead can eventually be |
