For instance:

let () = 
  let[@landmark] rec f () = ()
  and g () = f () in 
  g ()

will produce unused variable "f".
This is a bug in the ppx "translation".

On the other hand, the warning will disappear with:

let f = ()
let () = 
  let[@landmark] rec f () = ()
  and g () = f () in 
  g ()

this seems to be a bug in the ocaml compiler.

The "unused" checks are confused with "unlocated" code ocaml/ocaml#7482
