For the Nth time this year that this has come up, I'll point out yet again that this issue has already been discussed to death before:
[Python-ideas] proto-PEP: Fixing Non-constant Default Arguments http://mail.python.org/pipermail/python-ideas/2007-January/000121.html [Python-3000] pre-PEP: Default Argument Expressions http://mail.python.org/pipermail/python-3000/2007-February/005704.html Result: Evaluating the arguments at runtime rather than definition-time was deemed too magical; the backward compatibility issues make changes unlikely; it's hard to find an acceptable syntax. But hey, if some people want to have another go at it, best of luck.
