I frequently run into situations in both Test::Unit and RSpec where I want to assert that two arrays are equal, but order doesn’t matter; i.e., set equality rather than array equality.

This is one of those things that is simple, but only if you know where to look for it. There are a ton of emacs/clojure setup articles on the greater www, but many of them are out of date, and some of them are being explicitly deprecated.
