Hello,
I think this polymorphic comparison is quite easy to implement in the
following way:
#open "hashtbl";;
let c x y = (hash x) <= (hash y);;
#infix "c";;
#3 c true;;
- : bool = true
#[ "hello" ; "world" ] c 3.14159;;
- : bool = false
But, as Pierre Weis, I am wondering what to do with such a function...
Maybe
let c (x:'a) (y:'a) = (hash x) <= (hash y);;
would be more suitable ?
