Hi Chris,
includes? is in clojure.contrib.seq. Note that it runs in linear time.
This will feature prominently in the FAQ when I update it. :-)

Hi,
Is there a standard function to test to see if an object is an
element of a sequence? I'm looking for an equivalent of Haskell's
elem function.
I wrote my own (badly)...
(defn elem? [obj l]
(if (empty? l)
false
(if (= obj (first l))
true
(elem? obj (rest l)))))
...but it strikes me that there must be a standard function to do
this.
Cheers,
Chris
