You can -- but you must use a different syntax (as I showed in my
previous post).

Well, I don't know if I would describe the technique as "a mess", but
it can be done using nested invocations of Update_Element.

No, not really.  (That would be more true of the C++ STL vector
container.)  In the Ada case, a "vector" is simply a container that
directly supports random access.

But a vector (in Ada) is not a generalization of an array, so the
analogy doesn't hold.
