Modifying access to local variables

[Boris Boutillier]

Hi all,

I'm practicing python for a while and had a question, I looked in this
newsgroup but didn't find something helpful already posted so I give
it here :

What I wanna do is be able to write without error the following thing
:

def foo():
   x = z

z isn't define anywhere (not a global variable) and I want it to be of
special class, say Myclass.
So what I want the code to mean is the following :
def foo():
   z = MyClass()
   x = z

But this line of declaration is useless as all the variables I'll use
in the function will be MyClass object. Is there a way to avoid
declarations of variables in function (in my case, I'll have more than
a hundred ones).
I was thinking about something redifining a __getattr__ function
associated with local variables but I don't know if it is possible or
if there is another way to do it. The main idea is to avoid hundreds
of declarations lines.

Hope I made me clear, and thanks for answers.
