An interesting corner case here: ``` > (variable-not-in '|1| '|1|) '|12| ``` Which is the behavior I would expect (if a tad of a silly example).

Would it make sense to disable tracing for the menu-based student languages? If these problems don't exist in the #lang versions we can avoid this and #44 until those are...

From a prior discussion with robby, it sounds like we would at least like to move the invoking of the `error-display-handler` and `test-judgment-does-not-hold` over to redex proper. I would guess...
