Wow, thanks!  Sure!  I mean, I didn't really contribute much beyond
the concept - the implementation is really primitive (ripping apart
doctest's printed output and parsing its strings).  If it were going
to become a real part of IPython, it should probably be a little more
sophisticated - maybe creating a custom "out" function to pass to
``DocTestRunner.run`` so it wouldn't be so fragile, and so it could
accept some arguments/flags.  Or something like that.  This is my
first time looking inside doctest.py and I'm just trying to sound
smart.  :)

I'd also be interested in ideas about how it can look more
seamless/transparent to use - can the notebook somehow be set up to
automatically try to run it against all class and function definitions
found in any of its cells?  Then again, maybe it shouldn't be too
transparent - maybe it's good to let students see a little of testing
in action and that testing is awesome but not magic (though it could
be %magic).
