Oerk. This time hopefully a working version...
(defn get-in
([m ks]
(get-in m ks nil))
([m ks not-found]
(if-let [[k & ks] (seq ks)]
(let [candidate (get m k not-found)]
(cond
(identical? candidate not-found) not-found
ks (recur candidate ks not-
found)
:else candidate))
(throw (Exception. "Empty key sequence")))))
Sincerely
Meikel
