As I understand what you are saying it can be written like this:

A := A + B; equals

   function Add (A : Some_Type; B : Some_Type) return Some_Type;

while A += B; equals:

   procedure Add (A : in out Some_Type; B : in Some_Type);

Isn't this correct?

If so I think using a procedure is more clean (syntaxwise) than to use
+= which looks like a function IMHO.
