More fundamentally: It's nice to have the flexibility of non-zero
lower index bounds, but it does complicate the API a lot, and it
adds some extra run-time overhead - without adding any extra "power".

If we drop non-zero lower bounds, then "an internal" is just
a vector of integers, and no "interval API" is needed.
