I thought that is just because I don't use x in the function, but you are right it warns even if I use x
and I have the duplicate label:

# let foo ~x ~x () = x;;        
Warning 27: unused variable x.
val foo : x:'a -> x:'b -> unit -> 'b = <fun>

I think thats good enough for me now, I'll pay more attention to the unused variable warning.
