Delphi(or C#)'s method resolution clauses.

Java-style interface introduced in Ada2005 makes primitive names to
global.
Method resolution clause restore them to local.

type I1 is interface;
procedure X (Obj : I1);
type I2 is interface;
procedure X (Obj : I2);

type T is new I1 and I2;
procedure X (Obj : T); -- conflicted!!!

If method resolution clause exists:

type T is new I1 and I2;
overriding(I1.X) procedure X1 (Obj : T);
overriding(I2.X) procedure X2 (Obj : T);

X(I1(Obj)); -- calls X1
X(I2(Obj)); -- calls X2
