What substantial increase? There's already a check that winds up
raising an exception. Just make it empty an iterator

s.__setitem__(slice(None,None), generator_object)
where 'generator_object' is completely opaque, except that it will yield
0 to infinity objects in response to next() before raising StopIteration.
