What's the idiomatic way to handle cases where one has a macro rather than a function? For example: intent is as follows but does not work: (def args [false true false]) (apply or args) alternatives? a (eval `(or @~args)) b (reduce #(or %1 %2) args) any recommended? thanks, Pedro On

well I think the main advantage is memory. :-) Theoretically (I think), thread-per-connection servers can be very close to matching asynchronous servers in throughput, but they definitely require much more RAM to do so. RAM is one of the more expensive commodities to come by on VPS and cloud

(inc clojure.zip); clojure.contrib.zip-filter is a nice companion. Also, clojure.walk might be worth investigating. It provides no complex navigational facilities, so only some types of tree transformations are walkable, but for dealing with those, it's an absolutely fantastic tool. Sincerely,
