It turns out this is a result of your having updated the str_cmp answer=20=

checker to return an AnswerEvaluator object rather than a CODE=20
reference.  The check_string filter uses str_cmp the check the answer,=20=

but uses it as a CODE reference, so I changed that to=20
$ans_eval->evaluate($ans) and that took care of it.  I haven't looked=20
to see that there aren't other places where this might occur.
