Method to copy entire data object from element

[sliver]

Creating new bug per John Resig:  http://groups.google.com/group/jquery-dev/browse_thread/thread/a7d0544e287f662d

One possible approach would be to have $("el").data() return the entire data hash for the element, and $("el").data(hash) set the entire hash. Then the copy operation would just be:

$("#dst").data($("#src").data());

Would that set the #dst data object to the #src object, or would it use $.extend internally to make a copy?

Are events expected to be copied in this method as well? If so, each event will have to be rebound like we do in clone.
