So that means a view() function (with maybe a different name) -- however, that brings up the issue of where to put it. I'm not sure that it warrants being in builtins, but where does it belong? Maybe the collections module? And I really think the extra import would be a barrier.

It occurs to me-- and please quickly shut me down if this is a really dumb idea, I won't be offended-- `memoryview` is already a top-level built-in. I know it has a near completely different meaning with regards to bytes objects than we are talking about with a sequence view object. But could it do double duty as a creator of views for sequences, too?
