1197 for details. YYERROR is fine as it does not invoke this
1198 function.
1199 - If this state is a consistent state with a default action, then
1200 the only way this function was invoked is if the default action
1201 is an error action. In that case, don't check for expected
1202 tokens because there are none.
1203 - The only way there can be no lookahead present (in yychar) is if
1204 this state is a consistent state with a default action. Thus,
1205 detecting the absence of a lookahead is sufficient to determine
1206 that there is no unexpected or expected token to report. In that
1207 case, just report a simple "syntax error".
1208 - Don't assume there isn't a lookahead just because this state is a
1209 consistent state with a default action. There might have been a
1210 previous inconsistent state, consistent state with a non-default
1211 action, or user semantic action that manipulated yychar.
1212 - Of course, the expected token list depends on states to have
1213 correct lookahead information, and it depends on the parser not
1214 to perform extra reductions after fetching a lookahead from the
1215 scanner and before detecting a syntax error. Thus, state merging
1216 (from LALR or IELR) and default reductions corrupt the expected
1217 token list. However, the list is correct for canonical LR with
1218 one exception: it will still contain any token that will not be
1219 accepted due to an error action in a later state.
