I'm working with pysvn, and I'm trying to find a decent way to handle repositories that are only accessible via svn+ssh.

How exactly does Python evaluate class attributes? I've stumbled across an interesting quirk (in Python 2.5.2) that I'd like explained. I have a class with some attributes that are defined in terms of other, previously defined attributes. When I try using a generator object, Python throws an error, but if I use a plain ordinary list c...
