Design pattern:
	Command

Description:
	"Encapsulate a request as an object, thereby letting you parameterize
	clients with different requests, queue or log requests, and support
	undoable operations."

This pattern can be used with both classes and prototypes.

The simple way to implement this design pattern in Logtalk is to represent
commands as parametric object identifiers with the parametric objects
implementing the command protocol.
