I added a Scala solution since Haskell is already well represented.
Regarding exercises that are easier in OO, I don't think you'll find one
that a good Haskell programmer can't match in a functional style. But if
you make simulation the goal of the exercise (rather than writing a program

Do you know of an exercise where classes would add value? Something
fairly small, roughly similar in size to this exercise.
AFAICR, the motivating example for OO (in Simula) was simulating an
environment where different entities interact - I think the

This was the key point, I think.
In this example, there wasn't any significant behaviour that could be moved
to superclasses. For that matter, whether a

Hi all,
I'm in the process of learning how to approach problems from a
functional perspective, coming from an Object Oriented background
(mostly Smalltalk).
One of the general concerns/questions raised when talking to people in
a similar position is:
How do I design/model a problem when I don't
Challenge accepted! I have written a solution in Haskell; please merge :)
