Except that is precisely what the Python developers have asked
everyone not to do. So far the story is that the upgrade to Python 3
can be done largely automatic and a codebase for 2.x and 3.x can be
maintained automatically and kept in sync.

Once you introduce semantic instead of syntactic differences outside
Python 3 itself into the whole mix, it gets virtually impossible to
maintain a codebase that works on both 2.x and 3.x.

So while the Python 3 uptake is still slow, I think we shouldn't add
more roadblocks onto that path.
