The short answer is: don't do that! __init__.py may import any module, but  
other modules in the package should not import anything from __init__.py
The same rule applies to the main module in an application: it can import  
any other required module, but no one should import main.
If you don't follow those rules you may encounter some surprises.
You *can* break the rules and actually do what you want, but I would not  
reccomend it.
In this case, can't you switch the place where __version__ is defined? It  
looks like a constant, so you could have it actually defined in mommy.py,  
and inside __init__.py just import the value.
