[Tutor] Challenge supporting custom deepcopy with inheritance

[Michael H. Goldwasser]

Yesterday, I posted a question to python-list involving custom
deepcopies in an inheritance hierarchy.  I haven't received any
responses, so I thought I'd cross-post to see if anyone on tutor
has any thoughts.

To avoid splitting the thread, I'll simply reference the original post at
http://mail.python.org/pipermail/python-list/2009-May/714866.html
and ask for responses to be sent there.

With regard,
Michael
