Sorry, I was tired and didn't explain very well. Right now you have a "naked" (:use clojure.contrib.seq-utils) somewhere.
You want to use partition-by, but that's already in core, so you might just get rid of the :use altogether. But maybe there are some other functions in seq-utils that you do want to use --- in that case, do (:use [clojure.contrib [seq-utils :only [functions you want]]]) or (:use [clojure.contrib [seq-utils :only []]]) to avoid stepping on core and also to document what you actually use. If you really want the seq-utils version of partition-by, then you can do: (:use [clojure.contrib [seq-utils :as whatever]]) whatever/partition-by And if you really want to replace the core version with the seq version without any namespacing, do (:refer-clojure :exclude [partition-by]) (:use [clojure.contrib [seq-utils :only [partition-by]]]) does that help? --Robert McIntyre On Mon, Aug 30, 2010 at 2:43 PM, Chris Jenkins <cdpjenk...@gmail.com> wrote: > How would using the :only keyword help here?
