Are you implying that Ada, which has this feature (under the somewhat
misleading name of ``slicing''---it's a type of slicing, but a very
restricted type), suffices for array shifts?

How do you take an array x indexed from 0 to 10 and pass it to a
procedure indexed from -5 to 5 (presumably with a pointer to the 0th)?
I don't see a way to do this.

If it's there, my apologies; this is what I get for not spending a lot
of time with a language before talking about it. In that case the word
``Ada'' should be deleted from my postings on arrays versus pointers.
But I just don't see how it's done.
