  Why not:

      package Foo is
          type T is private;
  	  function X return T;
  	  function Z return T;
      private
          package Bar is
	    type Hidden is (X, Y, Z, W);
          end Bar;

          type T is new Bar.Hidden;
  	  function X return T is begin return T(Bar.X); end X;
  	  function Z return T is begin return T(Bar.Z); end Z;
          pragma Inline(X,Z);
      end Foo;

      Yes, I know that what he really wants is Discard_Names...
