was applied in 1.8 alphas and contains a new :load-ns option for defrecord and deftype but did not document that in the docstring.
This ticket adds documentation for that feature to the docstring.
Additionally, text should be added to http://clojure.org/datatypes.
Pulling into 1.8 as it would be nice to doc this in the release.
Modified docstring format slightly, retained attribution in -2 patch.
