Both Clojure and Clojure-Contrib are now available as nightly builds
from the Tapestry360 Maven snapshot repository.
To access the nightly snapshots in Maven, you must update your
pom.xml's repositories element (creating it as necessary):
repositories

I'd say to refactor clojure-contrib into a number of seperate modules;
individual modules (each with its own pom) could have their own
dependencies. Thus if you choose clojure-contrib-freechart, you get
that JAR (or compiled Clojure sources) plus the jfreechart dependency.
In this way you are
Looks like we need a macro:

Using regular and proper formatting assists in submitting patches.
A little Javadoc would be nice as well.

A relevant question is: what is the relative cost of locking and
blocking (in the pure Java approach) vs. the cost of retrying (in the
Clojure/STM approach).
I don't want to go out on a limb, having not looked at the Clojure STM
implementation. However, I would bet that the costs are roughly
I had a good time presenting an overview of Clojure at this years

A few questions from the crowd (of about 15 attendees) that I couldn't
accurately respond to:
1) What prevents thread starvation when using (dosync) and ref's?
It seems to me that conflicting
I'd like to remind people using Clojure and Maven that they can get
nightly builds of Maven via the Tapestry360 maven snapshot repository:

Personally, I've been noodling about what a Tapestry/Clojure hybrid
might look like.
I'd advise that you take a peek at Lift, a functional web framework
built on Scala.
I have some ideas about what a component based framework would look
like in a function world (note: this would be leaving JSPs

Qi is a kind of AOP layer that knits together concerns via a bit of

I have to wonder a bit about the ability to optimize. Everything
boils down to one of the seven or so basic forms. That's a lot of
function calls to do even small things, like adding numbers. You might
think that simple math would be optimized and inlined, but it isn't:
