(* To simplify Corify, it helps to apply a particular kind of renaming to functor
 * bodies, so that nested functors refer only to fresh names.  The payoff is that
 * we can then implement applications of those nested functors by evaluating their
 * bodies in arbitrary later contexts, even where identifiers defined in the
 * outer functor body may have been shadowed. *)
