Suggesting for overloading the assign operator

[Rim]

Everyone! Thanks a lot for the insightful and enlightening discussion.

I think the suggestion to solve the problem by using the __setattr__
special method will not work because it intercepts attribute
assignment of the form "self.attr = somthing", and not what I want,
which is "name = something".

John suggested to look at properties, this is the closest I can get to
the
behavior I am looking for, but from my understanding, that will let me
intercept "name.value = something" instead of intercepting "name =
something".

Thank you very much everyone.
