I see your point. Again, this is the weakest point of my proposal, we
should not discard all of it just because of that.

And maybe we can come up with something better.

E.G: I suggested before that iter() returns objects with advanced
semantics for [:] as an alternative to add slicing to generators.

Maybe the same objects can come with a chain() method, which is
explicit. Or provide an additional builtin function, which does help
with those issues if changing iter() is not possible.
