Subject: [Caml-list] Haskell class type simulation
Date: Thu, 21 Nov 2002 22:13:14 +0100	[thread overview]
Message-ID: <200211212213.14407.johan.baltie@wanadoo.fr> (raw)

Hi !

I'm currently looking for a way to simulate  the Haskell "class type" notion 
in OCaml i.e. the same kind of :

class Eq a where
    (==), (/=) :: a -> a -> Bool

class (Eq a) => Ord a where
    compare                :: a -> a -> Ordering
    (<), (<=), (>=), (>)   :: a -> a -> Bool
    max, min               :: a -> a -> a

For me it's a bit like module signature with an abstract type and an 
"extending" semantic and a type constraint.

Any hint ?
