Influences From Older Lisp-based Object Systems
Flavors (and its successor New Flavors) was the object system on the MIT Lisp Machine. Large parts of the Lisp Machine operating systems and many applications for it use Flavors or New Flavors. Flavors introduced multiple inheritance and mixins, amongst other features. Flavors is mostly obsolete, though implementations for Common Lisp do exist. Flavors was using the message passing paradigm. New Flavors introduced generic functions.
CommonLoops was the successor of LOOPS (from Xerox Interlisp-D). CommonLoops was implemented for Common Lisp. A portable implementation called Portable CommonLoops (PCL) was the first implementation of CLOS. PCL is widely ported and still provides the base for the CLOS implementation of several Common Lisp implementations. PCL is implemented mostly in portable Common Lisp with only a few system dependent parts.

Famous quotes containing the words influences, older, object and/or systems:
“However diligent she may be, however dedicated, no mother can escape the larger influences of culture, biology, fate . . . until we can actually live in a society where mothers and children genuinely matter, ours is an essentially powerless responsibility. Mothers carry out most of the work orders, but most of the rules governing our lives are shaped by outside influences.”
—Mary Kay Blakely (20th century)
“It is natural not to care about a sister certainly not when she is four years older and grinds her teeth at night.”
—Gertrude Stein (1874–1946)
“It is the nature of our desires to be boundless, and many live only to gratify them. But for this purpose the first object is, not so much to establish an equality of fortune, as to prevent those who are of a good disposition from desiring more than their own, and those who are of a bad one from being able to acquire it; and this may be done if they are kept in an inferior station, and not exposed to injustice.”
—Aristotle (384–322 B.C.)
“The geometry of landscape and situation seems to create its own systems of time, the sense of a dynamic element which is cinematising the events of the canvas, translating a posture or ceremony into dynamic terms. The greatest movie of the 20th century is the Mona Lisa, just as the greatest novel is Gray’s Anatomy.”
—J.G. (James Graham)
