struct DedupWithCount<I> {
    iter: I,
    last: Option<Option<<WithCount as CountItem<<I as Iterator>::Item>>::CItem>>,
    f: DedupPredWithCount2CoalescePred<DedupEq>,


§iter: I§last: Option<Option<<WithCount as CountItem<<I as Iterator>::Item>>::CItem>>

last is None while no item have been taken out of iter (at definition). Then last will be Some(Some(item)) until iter is exhausted, in which case last will be Some(None).
