Thanks; spoken like a man.
I strongly feel that this needs to be corrected in 2.5. Iterators
should have neither __len__ nor __nonzero__. I see mostly agreement
that this is a misfeature. We don't really want to start writing code
like this:
while it:
x = it.next()
...process x...
when we can already write it like this:
for x in it:
...process x...
do we?
Keeping a special API to allow a more efficient implementation of
__reversed__ is fine.
