Just to clarfiy, you're suggesting that we still change .keys()
.values() and .items() to iterators, right?

If so, +1.  I was also starting to get a bit nervous about the new
complexity of dict().  Putting the view-like behavior into the
collections module makes good sense.

I'm not *in*-sane. Indeed, I am so far *out* of sane that you appear a
tiny blip on the distant coast of sanity.
