What about augmenting the builtins on Python 2.4 with the any/all
functions and defaultdict class? That way our code would look like
Python 2.5 code, but still run on Python 2.4.

If our util.any/all are accurate replacements for any/all in Python 2.5
(which I think they are) then, as far as I can see, the only problem is
to make sure the compatibility code is loaded before the first access to
any/all. Perhaps hg.py could simply do the 'import py24compat' if it
detects we're on Python 2.4.
