Yes, that might well be a good heuristic to try, if you are interested to pursue this, Max. Making the function static means that it may be inlined, and that can make a tremendous difference by specializing the loop for that particular function. But that in turn only tends to happen if the enclosing function is inlined. Consider foldr: the real payoff comes when foldr is inlined, so that the function at the call site becomes visible.
