[ Does RM require contiguous allocation of arrays? I am not sure.]

Anyway, Robert Duff has already expressed what I meant in another
subthread:

"Vector and array are basically the same
thing (except vectors can grow), and it's annoying that you have to use
different syntax to deal with them.

In Ada, "array" is built in, and has all kinds of cool features
(aggregates, with full-coverage checking, for example).
It's annoying that vectors can't have all of those features."
