Python 2.x is not being type hinted.

You could say that simplifying the backwards-compatibility shims to remove Py 2.6 compatibility may make a small difference, but the syntax changes are not all that big between 2.6 and 2.7 (set literals, dict and set comprehensions, multiple context managers per `with` statement, that's it really).

So no, I don't think it makes a difference.
