If your domain model can be represented by a simple vector / map /
set, then you have a very rich set of tools (in Clojure) to operate on
your domain model. If your domain model is represented by fixed types,
you have to write all sorts of wrapper functions to be able to apply
those
Hi, I just (mostly) finished reading the Programming Clojure book and
while it gave a great overview of the language, I'm still at a loss
for how to design programs.
Maybe my mind has been polluted by OO concepts.
For example, I'm trying to figure out how to do polymorphism in FP.
Specifically,

You'll get better answers later but here is my take on it.

Maybe a combination of OO and static typing.

I was having this discussion on another list and it seems that the
less OO folks know, the easier they find FP... so you may well be
right :)

Why?
because polymorphism makes code suck less, if done well. see

Thanks, I have HTDP on my computer but after the first chapter I got
distracted and have been meaning to get to itI'll look for my
answers there! :)

Cool, thanks for the tips. More inline below:

If polymorphism is the appropriate solution, yes. But for a lot of

Almost any such graph library is going to be a bunch of functions that
operate on a data structure.

We're probably in violent agreement,
There are two very interesting threads over on the Scala mailing lists
at the moment that have some bearing on this thread - and I think
illustrate the two very different ways of thinking about types and
type systems:
