This particular alternative to the default argument hack has come up before, as has the "hidden parameters after '**'" approach. (I thought there was a PEP on this, but I can't find anything other than the reference in the description of Option 4 in PEP 3103 - however, there is a thread on the topic that starts as part of the PEP 3103 discussion at http://mail.python.org/pipermail/python-dev/2006-June/066603.html)
