New code should use (.close foo) instead of (. foo close), IIRC.
Sure, but it's an enhancement over existing code, so I've

Hello,
Seems like this might be a good time to say thanks to Laurent for all
the work he's done on CCW. FWIW, I've been using it for a while, and
never had any issues installing it (at least not from a clean
Eclipse), nor any of the other described issues.
So thanks Laurent, and keep up the

Your responses are all suggestive but I don't know where to go from here
so I am going to make one more cry for help -- and to this group rather
than the leiningen-specific one suggested by Mark because my basic
problem is really how-to-get-clojure/emacs-running-under-MacOsX.

I can't see the value in catching Throwable and then re-throwing it;
idiomatically Throwable is rarely caught. Looking at code example, the

Quick question...I am trying to populate a record with values provided
in a list. I'm definitely doing it the wrong way...but maybe there's
no good way to do it.
Here's what I do (clojure 1.2.0 by the way):
(defrecord Foo [x y z])
(Foo. 1 2 3)
#:user.Foo{:x 1, :y 2, :z 3}

Hi,
constructors (like methods) are not first class. You have to wrap it
in a factory function.
(defn make-foo
[a b c d]
(Foo. a b c d))
(apply make-foo [1 2 3 4])

Ok, I think I've got it - so basically all private variants should go
in contrib now and moving defn- now would break a lot of people's code
just for a little more coherency.
But in this case, I'd like def- to be included in clojure.contrib.def.
I dislike defvar as it's just name and docstring

If def- remains for historical reason, def- may be marked as
