Nice try, too bad it doesn't work. I would even prefer that one :

let arg = true
external is_bytecode : bool ->  bool = "%identity" "%boolnot"

let () =
   if is_bytecode arg then
     print_endline "Bytecode!"
   else
     print_endline "Native!"

The strange thing is that the function given by Kim also have fewer 
than 6 arguments.
