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.
