The following seems to do it; (defmacro with-thread [nm & body] `(let [thread# (Thread. (fn [] (do ~...@body)))] (if ~nm (.setName thread# ~nm)) (.start thread#) thread#))
(with-thread "foo" (println "HasdfasdfasdfasdfasdfasdfasdfasdfI")) #<Thread Thread[foo,5,main]> user=> HasdfasdfasdfasdfasdfasdfasdfasdfI Also, macroexpand-1 really helps when writing macros. You can see exactly how it's being expanded and it's then somewhat easier to debug; (macroexpand-1 '(with-thread nil (println "HasdfasdfasdfasdfasdfasdfasdfasdfI")) (clojure.core/let [thread__112__auto__ (java.lang.Thread. (clojure.core/fn [] (do (println "HasdfasdfasdfasdfasdfasdfasdfasdfI"))))] (if nil (.setName thread__112__auto__ nil)) (.start thread__112__auto__) thread__112__auto__) Regards, Adrian.
