I'd honestly like the ability to use X'Type; this would allow us to say som=
ething like this:

Procedure Swap( A, B : in out Some_Type ) is
  Temp : Constant B'Type :=3D B;
Begin
  B:=3D A;
  A:=3D Temp;
End Swap;

Yeah, I know, it's a little thing and you can do it with generics, etc. But=
 that's not entirely the point, the point is that this allows the declarati=
on of types dependent on objects... it provides some of the niceties of typ=
e-inference without having to resort to such lazy/possibly-error-prone meth=
odologies.
