(** "Recursive functions" are those functions [f] that might call either:
- themselves, or
- another function that in turn might call [f].
For example in the following simultaneous definition of [f] [g] and [h],
[f] and [g] are recursive functions, but not [h]:
[let rec f x = g x
and g x = f x
and h x = g x]
