 Description   

The lookup function in PersistentTreeSet behaves differently in clojurescript than in clojure when a custom comparison function is used. If two elements are evaluated as equal, one of then is in the set and we do a lookup on the other, clojure returns the element in the set, whereas clojurescript returns the lookup element.

(let [compare-quot-2 #(compare (quot %1 2) (quot %2 2))
s (sorted-set-by compare-quot-2 1)]
(get s 0))

Should return: 1
Returns: 0
