"parent" in a class __init__ def?

I'm not sure how it's a comparison to class variables.  So I wouldn't
worry about that.  I think there are some advantages to having the
parent as an instance member.  Intuitively, the name lookup on
self.parent.foo would be faster than if you passed in the object in
question - although I haven't tested this.  In short, there's nothin
wrong with doin it - and it helps in many situations.
