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. -- Maciej Sobczak * www.msobczak.com * www.inspirel.com
