This is probably more of a Java question than a Clojure question. I'm
thinking most people will want clojure-contrib in their classpath. I
tried this using SVN 1127 without success.

That's great -- happy it's in.
Quick impression: I like the improvements to clojure.main, especially
that forms from stdin & -e are evaluated after init files are loaded &
*command-line-args* is set.

Hi all, I work at Terracotta and I think there are many things about

focus on immutable data structures is particularly fascinating and

The documentation for commute says "Sets the in-transaction-value of
ref ...". This implies to me that when the transaction ends, the ref
will have its previous value.
(def myRef (ref 19))
(dosync (commute myRef inc)) -> 20
@myRef -> 20
Why isn't the value of the last line 19?

I was toying around with agents today, and I got a weird behavior:
agents hang clojure.lang.Script. Here's a simple demo script; if you
run this script, it'll print the vector and the program will be
hung.
(let [a (agent [])]
(doseq [i (range 10)]
(send-off a conj i))
(await a)

One big issue to note is that, because of Refs, Clojure agent
semantics can't simply be remoted the way Erlang processes can be.
This is because a message send could include a references to a Ref,
thus exposing mutable state remotely. This breaks, well, just about
everything.

But couldn't you just write some macros to wrap a message-passing

hi clojurians,

Rich,
I readily acknowledge the diversity of message passing frameworks for
Java.
Notwithstanding, I think it makes sense to think about distributed
message passing mechanism inherent to Clojure language, like the one
Erlang has.
It is Erlang abstraction of light-weight processes and extreme ease
I did some more testing on this and discovered some interesting
things...

Your call to a2 is not in tail position. You'll probably have
