That's why I proposed <0, 1, ..., 9> for repr(range(10)). (And I meant
the '...' literally, i.e. if there are more than 4 values, replace all
but the first two and the last with three dots. And yes, I mean that
str(range(4)) == '<0, 1, 2, 3>' but str(range(5)) == '<0, 1, ..., 4>'.

I'm not at all sure that we should go the same way for dict views
though. They are quite different beasts -- the fact that they change
depending on the underlying dict ought to be somehow emphasized, and
I'd be happier to keep these as they are in 3.0a4.
