ideal
     
        1. ideal deductive applicative language.  a language by pier
        bosco and elio giovannetti combining miranda and prolog.
        function definitions can have a guard condition introduced
        by ":-" which is a conjunction of equalities between
        arbitrary terms, including functions.  these guards are solved
        by normal prolog resolution and unification.  it was
        originally compiled into c-prolog but was eventually to be
        compiled to k-leaf.
     
        2. a numerical constraint language written by van wyk of
