My apologies if this is or has been well covered, but I'd like to know 
whether there has been consideration for allowing introspection of 
events already attached to elements or objects?

I'd like to be able to get the event types, attached function(s), 
whether capturing or not, etc., and possibly also access which events 
could come through the element via bubbling, or precede it by capturing.

I think this could be useful in IDEs, during debugging (and in tools 
such as Firebug), and also assist when one wishes to dynamically remove 
all events on an element. No doubt there could be a good number of other 
interesting use cases.

(This might be especially handy if Mozilla's toSource() could become 
standardized as well, even if it isn't able to be used to rebuild closures.)

thank you,
Brett Zamir
