Qualified expression?

   Access_Type'(new T)

Maybe something like this:

   function Allocate_In (Pool : in out Root_Storage_Pool'Class)
       return not null access T is
       type T_Ptr is access T;
       for T_Ptr'Storage_Pool use Pool;
       Ptr : T_Ptr;
   begin
       Ptr := new T;
       return Ptr.all'Unchecked_Access;
   end Allocate_In;
