Very nice. A good illustration of a lot of Clojure features too,
especially with the detailed follow-up:

Working in the web dev world, I'm fairly used to systems offering ways
to cache data for a period of time to improve performance - to reduce
database traffic, to reduce complex data manipulation. The pattern is
pretty much always:
if ( thing not in cache ) {
do expensive calculation / data loa

Yes, this is my main objection to maven and why I've resolutely stuck
with ant and managin

I think Leiningen does a great job of hiding maven. I initially wanted
to avoid Leiningen because of maven and when I was putting together
cfmljure (as a way to introduce Clojure to CFML developers :) I
initially documented the download ZIP, unzip, copy JARs approach but
then I reconsidered and upd

Since cfmljure got a mention...
Would folks be interested in a ready-to-run Jetty-based download that
ran CFML and Clojure out-of-the-box?
