Thank you for the correction and citation.

Yes, I was incorrect.
We have:
module rec F: functor (X:sig end) -> sig val f : int -> int end =
functor(X:sig end) -> struct
let f x = if x = 0 then 0 else M.f (x-1)
end
and M : sig val f: int -> int end = F(M)
This should imply interesting examples are available.
Best,
Keiko
