weakattr (weak attributes) are attributes that are weakly referenced by their containing object. they are very useful for cyclic references -- an object that holds a reference to itself.

I like the added functionality offered with weakattrs as defined. I'm not terribly in love with the syntax of their creation, and I'm curious as to how it plays with slots (not quite having the time to look at its implementation right now), but it is quite explicit, so I can get past that. It would allow us to say, "stop using del, use weakattrs", but I'm not sure how well that would work, generally.

Toss it out in python-list, I think some people over there would be able to offer more feedback.
