from __future__ import generators

Well, you only need 'from __future__ ...' in modules that actually use
generators, so the ratio is a lot closer to 1:1.

Hm... I don't have 2.2a installed or I'd just try this, but...  if I've
got a module that declares a generator:

--------- gen1.py ----------

from __future__ import generators

def g():
    for i in xrange(100):
        yield i
----------------------------

And then a second module that imports gen1 and uses that generator....

-------- gen2.py -----------
import gen1

for n in gen1.g():
    foo(n)
------------------------

Would gen2.py also require the __future__ statement?  Or, is gen1.g()
returning a "plain" iterator, thus rendering the __future__ irrelevant
in gen2.py ??

(Gotta install 2.2a sometime soon....  )
