Yes, AI-262, "private with". Already approved by the ARG. The example
would be written in Ada 0Y as:

   private package a.b is
      type hidden is <something>
   end a.b;

   private with a.b;
   package a.c is
      type not_hidden is private;
   private
      type not_hidden is new a.b.hidden;
   end;
