Is it possible to detach event listeners? I've got an event listener hooked up like this:

craft()-&gt;on('elements.populateElement', array($this, 'onPopulateElements'));


Is it possible to detach/deregister the listener? E.g. something like this (this doesn't work, but to illustrate):

craft()-&gt;off('elements.populateElement', array($this, 'onPopulateElements'));
Not possible currently, but there's a feature request.
