Good point. There is no static atom/listp distinction in Clojure. Still a
predicate function for "can yield a seq" is missing, to provide a flexible
flatten implementation like:
(defn my-flatten
([pred coll]
(mapcat (fn [p] (if (pred (first p)) (mapcat my-flatten p) p))
(partition-by pred coll)))
([coll]
(my-flatten sequential? coll)))
