Good Jonathan, something like this is on my mind but where I need to put
a piece of code like this?
I work with __bobo_traverse__ for some purposes but I would like a place
like __getattr__ because is where I go when I need an object's member
(__hasattr__ too) and __bobo_traverse__ need to returns an object not a
__getattr__ some of you (I don't remember how exactly, sorry) have said
is a member to use only if there are no other way and I'm a little
scared for that
What do you thing about?
