FYI, in clojure.contrib.seq-utils:
(defn includes?
"Returns true if s contains something equal (with =) to x."
[x s]
(if (some (fn [y] (= y x)) s)
true false))
Although I've found that whenever I use it, I'm better off using sets.
And I write "find" for vectors/sequences thus:
(first (filter #(some expression %) collection))
