Unlike regular transient sets, data.int-map transient sets do not support the IFn interface

Correct, the error here is in the example, but I will tweak the docstring to be more explicit about what its arg is.

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 [1])) 1)` works for me.

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 https://clojure.atlassian.net/browse/CLJ-700#icft=CLJ-700 is added.

This should be easy enough to fix, thanks.
