Today in the Intertweets (Nov 17th Ed.)

• #Clojure Support arbitrary functional destructuring via -> and ->> (here, via @fogus). This is just a proposal, and it would work like this:

user=> (let [(-> str a) 1] a)
"1"

user=> (let [[a (-> str b) c] [1 2]] (list a b c))
(1 "2" nil)

user=> (let [(->> (map int) [a b]) "ab"] (list a b))
(97 98)

• tweaked my bin/clj script to give formatted #clojure stacktraces. (here, via @mmcgrana) — Neat!

• How to optimize a Clojure program properly (here, via @cgrand) — Cristophe takes a look at Lau’s implementation of Brian’s Brain and looks for ways of making the code run faster. He achieves a 5x speed increase, so it’s worth looking at the proposed optimization techniques.
• Clojars: an alternative to Maven’s Central Repository for #clojure projects with much less hassle (here, via @tbatchelli)
