pass a jquery object as trigger data

 $('#elt').bind('z', function( event, obj) {

 $('#elt').trigger('z', $('#elt'));

I would expect the handler will display a jquery object (actually, the one I passed as a parameter). Instead, it displays the DOM #elt object.

additional parameters should be passed with an array.

$('#elt').trigger('z', [ $('#elt') ]);

But in this instance, it will be triggered in the context of #elt anyway.

If this is the case, it is incorrectly documented in the API documentation ( (emphasis mine):

"The event object is always passed as the first parameter to an event handler, but if additional parameters are specified during a .trigger() call, these parameters will be passed along to the handler as well. To pass more than one parameter, use an array as shown here. As of jQuery 1.6.2, a single parameter can be passed without using an array."

The functionality you describe does not work as intended, as a single param still requires an array to make it work. Here's a fiddle proving this:

The docs are wrong here. It's never been a good idea to pass something other than an honest JavaScript Array, although it works for simple values like numbers. The problem with passing a jQuery object is that it looks array-like to makeArray, but it's no Array.
