Python's not going to introduce a new keyword or __special__ method any
time soon (especially given the recent moratorium on language changes),
or break existing usages. I think a __future__ to import from would be
pretty safe. Besides, hopefully soon enough we could remove all those
imports again, as we're done upgrading.

We're just following the Python pattern here, the from __future__ import
from zope.component.__future__ import new_lookup
would clearly signal even to a completely unaware Python programmer that
something special is going on.
