supercombinators
     
        {Combinators} with coarser granularity than those proposed by
        {David Turner}.  A {functional program} is translated to a set
        of functions without {free variable}s.  The members of the set
        are selected to be optimal for that program.  Supercombinators
        were proposed by John Hughes at {University of Edinburgh}.
