I would expect l1 == l2, where l1 and l2 are both lists, to be
semantically equivalent to len(l1) == len(l2) and all(imap(operator.eq,
l1, l2)). Currently it isn't, and that was the motivation for this thread.
If objects that break reflexivity of == are not allowed, this should be
documented, and such objects banished from the standard library.
