Further, it's such an EASY thing to do -- the proposed
    a[b # c]
is EXACTLY the same as
    a[b:b+c]
so where's the added value to justify something as major
as adding a new operator...?

I'd much rather have the modest implementation change to
ensure that a[slice(b,b+c)] did just the same for all
sequences -- it's a rather surprising thing that it fails!
