Hi Bill,
You could do something like this:
(defn seq-xor-2-seqs
"Returns the unique values that are in one sequence but not the
other."
[x y]
(let [x (into #{} x)
y (into #{} y)]
(lazy-cat (clojure.set/difference x y)
(clojure.set/difference y x))))
Not sure this is more idiomatic, though. And I guess it would perform
worse with huge collections...
