Which is exactly why Christopher said from the start of this

Erm, did someone actually ask for something different? As far as I
can tell the original thread OP was asking for islice-maker
objects, which don't require the behaviour of slicing to change at
all. Quite where the demand for slice views has come from I'm not
at all clear.
That doesn’t make any difference here.
If you want slicing sequences to return iterators rather than copies,
that would break way too much code, so it’s not going to happen. A
different method/property/class/function that gives you iterators
would be fine.
We already have such. It's called itertools.islice().
I'm sorry, but you're missing the point here. You and Christopher seem
to be having fun discussing this at great length, and that's fine.
However at this point I've not grasped the proposal and I've lost the
will to even contemplate the details. What I have grasped is that no
one else has offered much opinion, so saying that "everyone else has
agreed at every step of the way" doesn't actually have the weight it
pretends to.
