Sorry. Still -1.
I read your defense, and I'm not convinced. Even Fredrik's support
didn't convince me.
Iterators are for single sequential access. It's a feature that you
have to import itertools (or at least that you have to invoke its
special operations) -- iterators are not sequences and shouldn't be
confused with such.
