   I think you miss the point here.  I expect that all systems will   
   integrate(diff(f(x),x),x) to get f(x), if f  is an anonymous function   
   name.  When f is pre-defined as some complicated   
   function, then the usual language semantics is to perform the   
   differentiation, to get   
   a more complicated function, which must be integrated.
