Common Lisp Object System

Common Lisp Object System (CLOS)

The object-oriented features introduced as a component for Common Lisp although the original proposal actually predates CL. It adds an optional fully featured object model to CL but what is unusual about it is that it is bolt-on, it is in other words a layer on top of the language rather than a language feature so a number of other LISP and Scheme variants have created or ported CLOS onto their systems as well.

Standards

• The original Common Lisp Object System Specification was written by Daniel G. Bobrow, Linda G. DeMichiel, Richard P. Gabriel, Sonya E. Keene, Gregor Kiczales, and David A. Moon; and was published in draft form on June 15, 1988. It is available in two parts, namely 1. Programmer Interface Concepts and 2. Functions in the Programmer Interface.
