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

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

AFAICR, the motivating example for OO (in Simula) was simulating an
environment where different entities interact - I think the case was

Being unfamiliar with git, I've submitted an AWK answer by e-mail.

Challenge accepted! I have written a solution in Haskell; please merge :)

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
