Yes using a separate class variable would transfer the problem to the class
level. But adding 10 class variables if I have 10 properties would be ugly.
Maybe I should reformulate the subject of this thread to "is there some python

Hi. I couldn't find a way to overwrite a property declared using a decorator in

For now, get started in Python 2.7. Write code with an eye to 3.x
portability, and you will be fine. You probably won't see 3.x
overtake 2.x for at least 3-4 years, and a decent amount of stuff is
still 2.x only. Since it sounds like you are a windows/net shop, go
ahead and use Iron Python.

So I would really like to accomplish the following:
run a program normally and keep track of all the imports that were
actually done.
I studied the PEP 302, but I'm still a bit confused about how to do it.

There are many complications with using them though. One of them in
