Thanks Sean and Meikel.
I tightened up the function a bit as a single function with multiple
arglist:
----------
(defn clear-cached-files3
([]
(dosync (alter file-seq-cache empty)))
([& ks]
(dosync (dorun (for [key ks] (alter file-seq-cache dissoc key))))
@file-seq-cache))
----------
I didn't want the dissoc to be lazy (I'd never expect the list to be that
long).
