LISP 2
     
        {LISP 1.5} with an {ALGOL 60}-like surface syntax.  Also
        optional type declarations, new data types including
        integer-indexed {array}s and character strings, partial-word
        extraction/insertion operators and {macro}s.  A
        {pattern-matching} facility similar to {COMIT} was proposed.
        Implemented for the {Q-32} computer.
