Bollards! A non-generic package may be the only instance of a design
concept:
package Stupid_Queue is
procedure Put (Item : in Integer);
function Get return Integer;
end Stupid_Queue;
[Properly documenting this specification and implementing the body are
left as exercises for the reader.]
This is an instance of the more general concept of a queue of integers.
This is a contrived example that should never be found in practice, but
application-specific cases in which neither extensibility nor multiple
instances are required are certainly not impossible to conceive.
