LISP
     Lots of Isolated Silly Parentheses (LISP, slang)
     
     

LISP n. [from `LISt Processing language', but mythically from `Lots of
   Irritating Superfluous Parentheses'] AI's mother tongue, a language
   based on the ideas of (a) variable-length lists and trees as fundamental
   data types, and (b) the interpretation of code as data and vice-versa.
   Invented by John McCarthy at MIT in the late 1950s, it is actually older
   than any other HLL still in use except FORTRAN. Accordingly, it has
   undergone considerable adaptive radiation over the years; modern
   variants are quite different in detail from the original LISP 1.5. The
   dominant HLL among hackers until the early 1980s, LISP now shares the
   throne with C. Its partisans claim it is the only language that is
   truly beautiful. See languages of choice.

   All LISP functions and programs are expressions that return values;
   this, together with the high memory utilization of LISPs, gave rise to
   Alan Perlis's famous quip (itself a take on an Oscar Wilde quote) that
   "LISP programmers know the value of everything and the cost of nothing".

   One significant application for LISP has been as a proof by example
   that most newer languages, such as COBOL and Ada, are full of
   unnecessary crocks. When the Right Thing has already been done once,
   there is no justification for bogosity in newer languages.

         LISt Processing language.
     
        (Or mythically "Lots of Irritating Superfluous Parentheses").
        Artificial Intelligence's mother tongue, a symbolic,
        functional, recursive language based on the ideas of
        lambda-calculus, variable-length lists and trees as
        fundamental data types and the interpretation of code as data
        and vice-versa.
     
        Data objects in Lisp are lists and atoms.  Lists may contain
        lists and atoms.  Atoms are either numbers or symbols.
        Programs in Lisp are themselves lists of symbols which can be
        treated as data.  Most implementations of Lisp allow functions
        with side-effects but there is a core of Lisp which is
        purely functional.
     
        All Lisp functions and programs are expressions that return
        values; this, together with the high memory use of Lisp, gave
        rise to Alan Perlis's famous quip (itself a take on an Oscar
        Wilde quote) that "Lisp programmers know the value of
        everything and the cost of nothing".
     
        The original version was LISP 1, invented by John McCarthy
         at MIT in the late 1950s.  Lisp is
        actually older than any other high level language still in
        use except Fortran.  Accordingly, it has undergone
        considerable change over the years.  Modern variants are quite
        different in detail.  The dominant HLL among hackers until
        the early 1980s, Lisp now shares the throne with C.  See
