Clojure quick tip: efficiently find last element in vector satisfying some condition

Trivial, but I keep forgetting about rseq:

user> (first (filter #(even? (do (println "x:" %) %)) 

                     (rseq (vec (range 1 100)))))

x: 99

x: 98

98

user> 

Vec is very nice; it'll alias JVM arrays. Anyway, doing (last (filter ..)) would traverse the entire vector which isn't very effective.

PS: Merry XMAS. :)
