OK, this might do it. But is a generator "better"?
(I assume accuracy is the same, so what about speed?)
def ireduce(func, iterable, init=None):
if not init:
iterable = iter(iterable)
init = iterable.next()
yield init
elif not iterable:
yield init
for item in iterable:
init = func(init, item)
yield init
