Thanks @zakarumych for suggestion!
I think it would be good: it's more convenient to not require this, and in some cases the size hint can be better then ExactSizeIterator. For example, repeat() doesn't implement it, so repeat().take() is unusable with the exact size, but it does in fact have the exact size, and the size_hint() reflects that nicely.
