Meikel,
Thanks for the tip. I like the look of doseq even better... gets rid of one
level of nesting. I used it on another version of the function but didn't
think to use it this time.
(defn clear-cached-files
([]
(dosync (alter file-seq-cache empty)))
([& ks]
(dosync (doseq [key ks] (alter file-seq-cache dissoc key)))
@file-seq-cache))
