Why shouldn't it give '(3 3 3)? It looks like you've introduced a fairly arbitrary distinction between the first and second arguments to a normally-symmetric function, intersect. And you would get the same behavior by using one of my suggestions:
user> (filter (set [1 2 3 3 3]) [3 4 3 5]) (3 3) user> (filter (set [3 4 3 5]) [1 2 3 3 3]) (3 3 3) As a side note, Clojure rarely uses quoted lists for data structures: vectors are easier for a number of reasons.
