That's been considered before, in relation to strings.
The stumbling block is the problem of a view of a
small part of the object keeping the whole thing
alive and using up memory.

While having a separate way of getting slice-views
could be useful, I think it would be too big a
change in semantics to make it the default
behaviour of slicing notation.
