fusion
     
         a program transformation where a composition
        of two functions is replaced by in-lining them and combining
        their bodies.  e.g.
     
        	f x = g h x	==>	f x = g 2  x
        	g x = x + 1		f x = 2  x + 1
        	h x = 2  x
     
        this has the beneficial effect of reducing the number of
        function calls.  it can be especially useful where the
        intermediate result is a large data structure which can be
        eliminated.
