Thanks.  So I could maybe have a property associate with an
interpreter box, such that returned output would be recognized as
"correct" (e.g. 42) or not.  Depending on the output, the next page
might be different.

At present, only standard "doctest" are run with an "expected" output.  When run successfully, a "custum" message appears.  It would be fairly easy to change this so that a link to a new page appears upon successful completion.  Or, it might be modified so that it links directly to the next page...

Note that the limitation to doctests should not be a big limitation in practice.  Usually, students will be ask to write a function that produces a certain result when called.  So, in the case you mention, the doctest might be:
"""
>>> print student_function()
42
"""
Until the student writes a function (named student_function!) that returns 42, no link to the next page would be present on the page.
----------
I see the interpreter prompt as an invitation to explore, rather than a testing environment.

If you have some "mock tutorial" (i.e. a series of exercises) that you can give me (perhaps off-list), I could see if Crunchy Frog could (as is) produce the type of tutorial that you'd want.  If not, it could be the next feature I implement ;-)
