Description:

GOOPS is the object oriented extention to Guile. Its implementation is
derived from STk-3.99.3 by Erick Gallesio and version 1.3 of the
Gregor Kickzales Tiny-Clos. It is very close to CLOS, the Common Lisp
Object System but is adapted for the Scheme language.

Briefly stated, the GOOPS extension gives the user a full object
oriented system with multiple inheritance and generic functions with
multi-method dispatch. Furthermore, the whole implementation relies
on a true meta object protocol, in the spirit of the one defined for
CLOS (Gregor Kiczales: A Metaobject Protocol).
