Common Lisp
     
         A dialect of {Lisp} defined by a consortium of
        companies brought together in 1981 by the {Defence Advanced
        Research Projects Agency} (DARPA).  Companies included
        {Symbolics}, {Lisp Machines, Inc.}, {Digital Equipment
        Corporation}, {Bell Labs}., {Xerox}, {Hewlett-Packard},
        {Lawrence Livermore Labs}., {Carnegie-Mellon University},
        {Stanford University}, {Yale}, {MIT} and {USC Berkeley}.
        Common Lisp is {lexically scoped} by default but can be
        {dynamically scoped}.
     
        Common Lisp is a large and complex language, fairly close to a
        superset of {MacLisp}.  It features {lexical binding}, data
        structures using defstruct and setf, {closures}, multiple
        values, types using declare and a variety of numerical types.
        Function calls allow "&optional", keyword and "&rest"
        arguments.  Generic sequence can either be a list or an
        {array}.  It provides formatted printing using escape
        characters.  Common LISP now includes {CLOS}, an extended LOOP
        {macro}, condition system, {pretty printing} and logical
        pathnames.
     
        Implementations include {AKCL}, {CCL}, {CLiCC}, {CLISP},
        {CLX}, {CMU Common Lisp}, {DCL}, {KCL}, {MCL} and {WCL}.
