the only way this function was invoked is if the default action
924
is an error action. In that case, don't check for expected
925
tokens because there are none.
926
- The only way there can be no lookahead present (in yychar) is if
927
this state is a consistent state with a default action. Thus,
928
detecting the absence of a lookahead is sufficient to determine
929
that there is no unexpected or expected token to report. In that
930
case, just report a simple "syntax error".
931
- Don't assume there isn't a lookahead just because this state is a
932
consistent state with a default action. There might have been a
933
previous inconsistent state, consistent state with a non-default
934
action, or user semantic action that manipulated yychar.
935
- Of course, the expected token list depends on states to have
936
correct lookahead information, and it depends on the parser not
937
to perform extra reductions after fetching a lookahead from the
938
scanner and before detecting a syntax error. Thus, state merging
939
(from LALR or IELR) and default reductions corrupt the expected
940
token list. However, the list is correct for canonical LR with
941
one exception: it will still contain any token that will not be
942
accepted due to an error action in a later state.
