Yeah, they changed that from clojure 1.1 and it's really annoying --- as far as I know, your only options right now are to either select exactly which functions from seq-utils you want using the :only keyword, or if you really want to use the seq-utils version you can use refer-clojure and the :exclude keyword. Or, you can use the :as keyword in the :use form to qualify the import so that you don't actually replace anything.
If you accidently get this warning and don't want to restart the repl you can do (ns-unmap 'your-namespace 'offending-function), fix the naked import, and reload. --Robert McIntyre On Mon, Aug 30, 2010 at 5:54 AM, Chris Jenkins <cdpjenk...@gmail.com> wrote: > Since I switched to Clojure 1.2, I see an error message whenever I try to > reload a source file that imports anything.
