Hi, I have recently discovered Functional Programming
and the Language Haskell. I was wondering if anyone
could reccomend some good tutorials.
Thanks..

It's certainly possible to define a more general interface, and the
theoretical work does. However the arrow interface is already very
general, and the question is whether an

Can't we write something like :
class Cartesian p where

module using the syntax:

But is it somehow possible to re-define this to be
