jQuery Expression Reference

Does anyone know if there is a way to get the expression that returned an object in jQuery from within it’s handler?
Example:
$('body > a').click(function() {
// Is there any way I can alert 'body > a' in here?
// Perhaps something like: alert($(this).expression); ?
});

I don’t remember any method for it, and looking at the source, I don’t think it save it somewhere.

[...] a few weeks ago I was looking for a way of accessing the selector from within the method, and now you can do it. [...]
