What steps will reproduce the problem?

2. attempt to import it
3. observe @collections._recursive_repr() being used while 
collections._recursive_repr was expected 

What is the expected output? What do you see instead?
It should have worked

What version of the product are you using? On what operating system?
On python 2.7.1 OS X Lion

Please provide any additional information below.
The decorator should not be called there IMHO (compatibility.py)
