A single model---dividing types into prototypes and traits---supports sharing of behavior and extending or replacing representations. A natural extension, dynamic object inheritance, can model behavioral modes. Object inheritance can also be used to provide structured name spaces for well-known objects. Classless languages can even express "class-based" encapsulation. These stylized uses of object inheritance become instantly recognizable idioms, and extend the repertory of organizing principles to cover a wider range of programs. 1 Introduction Recently, several researchers have proposed object models based on prototypes and delegation instead of classes and static inheritance [2, 9, 11, 14, 15, 18]. These proposals have concentrated on explaining how prototype-based languages allow more flexible arran...
