Actually it does:

python2.5
Python 2.5.2 (r252:60911, Apr 17 2008, 13:15:05)
[GCC 4.2.3 (Debian 4.2.3-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
 >>> def foo(with=5):
<stdin>:1: Warning: 'with' will become a reserved keyword in Python 2.6
...     pass
...

So while I'm generally happy with getting zope and python developement
better in sync it seems we have been too fast here since I believe
python2.5 migration is actually still in process and now you are heading
for 2.6? Doing it one after the other should already ruled out such
problems.

I wonder what can of worms is waiting in the restricted python area.
