Object Lisp was a computer programming language, a dialect of the Lisp language. It was an object-oriented extension for the Lisp dialect Lisp Machine Lisp, designed by Lisp Machines, Inc. Object Lisp was also an early example of prototype-based programming.
It was seen as a competitor to other object-oriented extensions to Lisp at around the same time such as Flavors, in use by Symbolics, Common Objects developed by Hewlett-Packard, and CommonLoops, in use by Xerox.
Object Lisp was also used in early versions of Macintosh Common Lisp. There, the user interface toolkit was written using Object Lisp.
Famous quotes containing the words object and/or lisp:
“Pleasure cannot be shared; like Pain, it can only be experienced or inflicted, and when we give pleasure to our Lovers or bestow Charity upon the Needy, we do so, not to gratify the object of our Benevolence, but only ourselves. For the Truth is that we are kind for the same reason as we are cruel, in order that we may enhance the sense of our own Power.”
—Aldous Huxley (1894–1963)
“Taught me my alphabet to say,
To lisp my very earliest word,”
—Edgar Allan Poe (1809–1849)
