Is it possible for information from one run of a grader, within the same quiz, to be passed from one CHECK to the next? In particular...
I would like to allow CHECK to indicate that -some- answers are incorrect, but not necessarily to identify all incorrect answers. On the next CHECK (if there is one), I would like to do the same, but only within the answers already flagged (ie by the first CHECK). And so on.
That's intended to prevent the students' "accumulating" hints from one CHECK to the next.
More generally, there are other situations in which it would be useful for "this" CHECK to be able to remember what the "previous" CHECK saw.
I have experimented with writing a file, but (not unexpectedly) it seems to be removed in between CHECKS.
Maybe there could be a component of stepinfo (which my CR version does not yet have) that brings in to 'this' CHECK a json'ed string passed out in a 'forNextTime' entry in the results dict of the 'previous' CHECK?
