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 ;-)
