Reflective Composition: the declarative composition of roles to unify objects, roles, & aspects

Simon Holland, The Open University, Milton Keynes, United Kingdom

As bases for object-orientation, both class-based and prototype-based organization have limitations. We argue that Roles have significant benefits as a foundation for organizing objects, and that these benefits can be realised most flexibly using logic meta-programming. This makes it possible to reduce redundancy and subsume aspects.
