What is your point. Any problem solved in a functional style can
also be solved in a pure interative style. So you having written
something in an interative style doesn't contradict Newton-Raphson being 
expressable in a functional style.

That doesn't prevent you from passing state along as a parameter,
usualy in some helper function.
