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 {crock}s. When the {Right Thing} has already been done once,
   there is no justification for {bogosity} in newer languages.
