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.
