This revision is not correct. Checking of .is_last must be done after the first call of next().

if it.is_begin:
    return False
it.decrement()
prev, v = it.object, next(it)
if it.is_last:
    return False
succ = next(it)

well, say it points to element 6, then

it.is_begin is false
it.decrement() -> it now points to element 5
prev = it.object -> prev points to element 5
v = next(it) -> v points to element 6; it points to element 6 (remember here that next() increments first, and then does the lookup)

so if it.is_last is true now, it would have been true at the top (and vice versa).

So I believe my solution is correct (tests suggest this too).

This line of code has to be:

prev, v, succ = next(it), next(it), next(it)
kjym3: This line of code has to be: ``` prev, v, succ = next(it), next(it), next(it) ```
v = it.object fe = v.get_fedge(prev)
it.increment()

return False
fe = v.get_fedge(it_prev.object)
