Hi Alex,
great to hear that there are more clojurians going pycon :). I'm
currently attending the pycon tutorial sessions and I'm staying until
sunday the 13th. Just let me know when you're here and where to meet.
Are the more clojurians wanting to join?
Cheers,
Erik

Hi,
see http://paste.pocoo.org/show/227866/
You just have to write your macro so that it expands into multiple
defs. Remember, macros work at compile time, so they are not the same
as eval. And from your code, I could not see your intentions, your
prepare-2 macro seems somehow wrong to me. Maybe
I'd vote for swing and against anything that abstracts away the
toolkit so that you can switch the backend.
Implementing a clojure wrapper for the apache pivot toolkit gave me
a little insight on at least two GUI toolkits, namely swing and
pivot. Despite their goal of displaying widgets on a 2 di
Hi,
Not really mechanisms, but two Idioms will help you with your problem:
Either wrap the defn in a let:
(let [U (gen-matrix [1 2 2 -2 -1 -2 2 2 3] 3 3)
A (gen-matrix [1 2 2 2 1 2 2 2 3] 3 3)
D (gen-matrix [-1 -2 -2 2 1 2 2 2 3] 3 3)
S (gen-vector [3 4 5])]
(letfn [(prims-fro

Unfortunately not for all operations. For example, clojure.set/join
uses its own index function, which builds an

hi,
you could use a simple class signature generator and then run javadoc
on it:
(def javadoc-strings (atom {}))
(defn javadoc [class name & body]
(swap! javadoc-strings update-in [class] #(conj (or % []) %2) [name
(apply str body)])
nil)
(defn -myMethod
"My cool documentation"

Hi,
I guess clojure creates a new classloader for each eval to make
redefining deftypes possible.
Is your requirement somehow related to applets or webstart or other
sandboxes environments?
