Chouser's solution works well, but I found that you can end up
with an empty string sometimes or never getting the maxlength
that you passed in.
1:2 user=> (take 3 (seq-of-rand-strings 10))
("ngene" "" "dwlbzndqx")
I added an inc before calling the take and that clears things up.
(defn seq-of-rand-strings [maxlength]
(repeatedly (fn []
(apply str (take (inc (rand-int maxlength))
(repeatedly #(char (+ (int \a) (rand-int
26)))))))))
