This misses a central point. Slices in Ada can only be
applied to one dimensional arrays. This (very
understandable) restriction is a significant one in
the context of numerical codes dealing with multi-
dimensional arrays.
The reason for the restriction is of course that otherwise
strides are not known at compile time in many cases where
they are known now, and that is a worrisome inefficiency.
(this has been well studied in the context of Algol-68,
which as far as I know was the first main stream language
to allow general slicing).
