A word of clarification: __future__ isn't about experimental
features.  Instead it is for bleeding edge users to use a new feature
in release X even though the feature won't be standard until release
Y, where X < Y.

If we want to do experimental stuff, we should probably do something
like:

from __possible_world__ import __future__
from __future__ import ...
