How would using the :only keyword help here? Just to be clear, the problem here is that attempting to load my source file the second time fails (loading the first time having succeeded, albeit with a few warnings about replacing symbols from clojure.core), which makes it very difficult for me to use swank-clojure, for example, because I can't hit C-c C-k twice on the same file.
Here is the failure when I try to load the file for the second time: java.lang.IllegalStateException: partition-by already refers to: #'clojure.contrib.seq-utils/partition-by in namespace: test.core (core.clj:1) So here's my main question: If I'm working in the REPL and I edit a file that I've previously loaded, how can I cause the file to be reloaded without hitting that error? If my .clj file doesn't :use any other clojure modules then reloading works fine but, if it imports anything, then the second (load-file...) fails.
