And this was one reason that I didn't put up any arguments at Ada Europe
2002 for the Ada 95 Booch Components to form a basis for Ada.Containers
- you'd need 3 instantiations, one after the other.

--  A company's Fleet holds a number of Cars.

   with BC.Containers.Collections.Bounded;
   with Cars;
   package My_Fleet is

      use type Cars.Car;

      package Abstract_Car_Containers
      is new BC.Containers (Cars.Car);

      package Abstract_Car_Collections
      is new Abstract_Car_Containers.Collections;

      package Fleets
      is new Abstract_Car_Collections.Bounded (Maximum_Size => 30);

      The_Fleet : Fleets.Collection;

   end My_Fleet;

The other was a lack of consistency in the implementation (Length?
Size?).
