[Haskell-cafe] Thread on scala ml: Usefulness of OOP

Hi all, I'd like to mention an interesting thread on the scala mailing list about usefulness of OOP. http://www.nabble.com/-scala--usefulness-of-OOP-td23268250.html Martin Odersky, scala creator, advocates the use of OOP using an interesting toy problem. I would be very interested about the haskell point of view on the topic. Is there any haskell guru that wants to take a stub at the problem or give his opinion? Thanks Paolo
