Thanks John. I mined contrib for java-util/file and duck-streams for
several functions as well.

Tomorrow I'll add a bunch more file functions and tests.

ITYM
t (if (= (class to) File) to (File. to))]
for that

Check out clojure.contrib.duck-streams/reader and clojure.contrib.duck-
streams/writer (http://richhickey.github.com/clojure-contrib/duck-
streams-api.html).
They'll give you a java.io.BufferedReader or a java.io.PrintWriter
which is usually what you want with a file. If you have some other
use,
Oh, maybe this as-file method already exists in clojure.contrib,
honestly I don't know and don't have the time to search right now,

Suggestion :
move and generalize the problem by creating an as-file multifn that may take
String, File , and maybe other things later ...
(defmulti as-file type)
(defmethod as-file String [from] (File. from))
(defmethod as-file File [from] from)
(defn mv [from to]
(let [ [from to] (map as-file
Here is another question on when you would use a multi-method. I want the
mv function to accept a java.io.File or a String for either of the two
parameters and here are the options I came up with:
-(defmulti mv (fn [from to] [(class from) (class to)]))
(defmethod mv [String String] [from to]
