Let's leave C++ aside then.

Imagine I haven an *array* of Person(s) and I do this:

Swap (People (X).Salary, People (Y).Salary);

This is Ada.

(is it value semantics for you, btw?)

Now I want to do the same with vector.

In other words, I want to use Ada in the Ada spirit.
What kind of mess do you recommend to achieve it?

If we realize that vector is a generalization of array, is it
revolutionary to expect that the common functionality should have
common interface?

The C++ example was just... an example. I'm sorry if it distracted you
from the real issue.
