The elementary structures include object-oriented classes, interfaces and mixins, all of which can specify one or more methods.

The “easy to use” aspect relies on classes, to be constructed by specification; on interfaces, to declare an API and to define the essential coupling in an extensible framework; and on mixins, to address cross-cutting concerns and the separation of concerns.
