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 
pattern.

I think:

   from zope.component.__future__ import new_lookup

would clearly signal even to a completely unaware Python programmer that 
something special is going on.

[Marius spelled it better than I did; no need to double underscore 
__new_lookup__]
