This should be easy enough to fix, thanks.

In theory, contains? is also supposed to work for transient sets: http://dev.clojure.org/jira/browse/CLJ-700
So while you are adding interfaces to data.int-map transient sets, you may want to add that one as well so that the behavior will match once CLJ-700 is added.

The original example looks like a typo. The argument to dense-int-set should be a collection, not a long so that explains the exception. Maybe the doc string could be more explicit.

((transient (clojure.data.int-map/dense-int-set (link: 1))) 1) works for me.
