I've just checked in a different solution with the use_2to3 option of 
Distribute, which creates a Python 3 version at build time.

Your solution using python-modernize to create a codebase that runs on 
both versions with the help of six could be a better idea, though.

But the main difficulty we're facing is the semantics of the String and 
Unicode validators under Python 3. Should we provide Bytes and String 
validators under Python 3 instead? How can we create a documentation 
that covers both versions of the validators with the automatic tools? 
I'm wondering whether creating a separate formencode3 library for Python 
3 could make more sense?
