Altough I'm not the OP, thanks a lot to everyone, I've learned much in 
this thread. But there's still something that puzzles me, I just realized.

In the snippet above (taken from the Python doc 
http://docs.python.org/lib/built-in-funcs.html), self.__x is 
initialized, but never used. I would appreciate any explanation for this.
