   Joy
      <language> A functional programming language by Manfred von
      Thun.  Joy is unusual because it is not based on lambda
    calculus, but on the composition of functions.  Functions
      take a stack as argument, consume any number of parameters
      from it, and return it with any number of results on it.  The
      concatenation of programs denotes the composition of
      functions.  One of the datatypes of Joy is that of quoted
      programs, of which lists are a special case.
