Does this apply to:

let () = ...

code?  I assume these aren't really "toplevel functions".

More seriously, what about toplevel functions which aren't referenced
outside the code (they may even be made private using an .mli file).
I have a LOT of code which does this sort of thing:

let run r =
  let q = new cgi r in

  (* ... blah blah the CGI script ... *)

(* Register the script's run function. *)
let () =
  register_script run

The toplevel 'run' function is there, but never referenced directly
from outside the code, although of course it is called from outside
the code.
