If you have an answer checker hash...
Actually let me pause here, I'm not sure I am using the right vocabulary. What I mean is something like when $m is a math object, and the object $m->cmp().
So when you have that thing, how can you verify that it actually accepts $m as a correct answer? This is for situations where the answer checker is custom. Some random version of the problem may be buggy and not take $m. I'd like to wrap it all in a loop and check that if $m is not counted as correct, it should re-randomize.
I'm thinking it could be something like:
until ($m->cmp($m) == 1);
but my experiments are suggesting that is not the right syntax.
