By watching OCaml work, and studying the compiler, I've seen it inline
many small functions, even when they are defined in other modules. I
pretty much like this, but I find only one minor inconvenience about the
way OCaml inlines. It is this one: say that you have

	module Foo = struct
	let ap_succ f n = f (n +. 1.0)
	let test a =
	   let my_f x = cos x
	   in ap_succ my_f a
	end

After inlining, the result is not a sort of
	let test a = cos (n +. 1.0)
but something like
	let my_f x = cos x
	let test a = generic_apply my_f (a +. 1.0)
It is even worse if `my_f' uses, for instance, `a', because then a
closure is built, which would not be necessary. I think this could be
solved by making the `inliner' a bit smarter and re-inlining the
functions that are applied. This would make it attractive and efficient
to write small useful functions in separate modules.
