<http://lists.gnu.org/archive/html/bison-patches/2009-12/msg00024.html>
1368
for details. YYERROR is fine as it does not invoke this
1370
- If this state is a consistent state with a default action, then
1371
the only way this function was invoked is if the default action
1372
is an error action. In that case, don't check for expected
1373
tokens because there are none.
1374
- The only way there can be no lookahead present (in yychar) is if
1375
this state is a consistent state with a default action. Thus,
1376
detecting the absence of a lookahead is sufficient to determine
1377
that there is no unexpected or expected token to report. In that
1378
case, just report a simple "syntax error".
1379
- Don't assume there isn't a lookahead just because this state is a
1380
consistent state with a default action. There might have been a
1381
previous inconsistent state, consistent state with a non-default
1382
action, or user semantic action that manipulated yychar.
1383
- Of course, the expected token list depends on states to have
1384
correct lookahead information, and it depends on the parser not
1385
to perform extra reductions after fetching a lookahead from the
1386
scanner and before detecting a syntax error. Thus, state merging
1387
(from LALR or IELR) and default reductions corrupt the expected
1388
token list. However, the list is correct for canonical LR with
1389
one exception: it will still contain any token that will not be
1390
accepted due to an error action in a later state.
