I believe duck-streams is deprecated since clojure 1.2. You may want
to consider bringing back f-to-seq, which can be simplified slightly
using reader from clojure.java.io:
(ns clojure.example.anagrams
(:use [clojure.java.io :only (reader)])
(:gen-class))
(defn f-to-seq [file]
(with-open [
Hi Meikel, Nicolas, and Justin,
Thank you for the great feedback! I learned a lot. I was puzzled about
(update-in (update-in)) and after doing that the -> operator makes a
lot of sense. The reduce is clever and fits nicely as well.
I dropped the function that read in the lines of the file and used

Damon reply to me and not the list, so I forward.

Meikel's suggestions are all good and I would follow them.
There are a number of built-in functions you can take advantage of if
you're using 1.2 (they're also available in contrib for 1.1):
clojure.string/lower-case
clojure.java.io/reader -- obviates java.io.BufferedReader and friends:
(reader "

Do you need the doall?

Hi Everyone,
I'm looking for some feedback on a small get-your-feet wet program I
wrote in clojure (my first). In particular, I hope to get feedback on
how to better make use of clojure's data structures and functional
programming in general.
Below is the toy program and the sample output. It read
