Hi everybody,

Typically, when you declare:

type card =
  | Card of int
  | Jack
  | Queen
  | King
  | Ace
  ;;

The relation you wish is:

Card(2) < ...< Card(10) < Jack < Queen < King < Ace

And that's what you get when using F#.

However when using OCaml here is what you get:

Jack < Queen < King < Ace < Card(2) < ...< Card(10)

And the work-around is: 

type card =
  | Card of int
  | Jack of unit
  | Queen of unit
  | King of unit
  | Ace of unit
  ;;

Is this a bug or a feature ?
Will it change in a foreseable future ?
