1217 - Assume YYFAIL is not used. It's too flawed to consider. See
1218 <http://lists.gnu.org/archive/html/bison-patches/2009-12/msg00024.html>
1219 for details. YYERROR is fine as it does not invoke this
1220 function.
1221 - If this state is a consistent state with a default action, then
1222 the only way this function was invoked is if the default action
1223 is an error action. In that case, don't check for expected
1224 tokens because there are none.
1225 - The only way there can be no lookahead present (in yychar) is if
1226 this state is a consistent state with a default action. Thus,
1227 detecting the absence of a lookahead is sufficient to determine
1228 that there is no unexpected or expected token to report. In that
1229 case, just report a simple "syntax error".
1230 - Don't assume there isn't a lookahead just because this state is a
1231 consistent state with a default action. There might have been a
1232 previous inconsistent state, consistent state with a non-default
1233 action, or user semantic action that manipulated yychar.
1234 - Of course, the expected token list depends on states to have
1235 correct lookahead information, and it depends on the parser not
1236 to perform extra reductions after fetching a lookahead from the
1237 scanner and before detecting a syntax error. Thus, state merging
1238 (from LALR or IELR) and default reductions corrupt the expected
1239 token list. However, the list is correct for canonical LR with
1240 one exception: it will still contain any token that will not be
1241 accepted due to an error action in a later state.

1092 that there is no unexpected or expected token to report. In that

1094 - Don't assume there isn't a lookahead just because this state is a
1095 consistent state with a default action. There might have been a
1096 previous inconsistent state, consistent state with a non-default
1097 action, or user semantic action that manipulated yychar.
1098 - Of course, the expected token list depends on states to have
1099 correct lookahead information, and it depends on the parser not
1100 to perform extra reductions after fetching a lookahead from the
1101 scanner and before detecting a syntax error. Thus, state merging
1102 (from LALR or IELR) and default reductions corrupt the expected
