            Bug ID: 25593
           Summary: Access to event listeners in the EventTarget
           Product: WebAppsWG
           Version: unspecified
          Hardware: PC
                OS: Windows NT

Any plans do this in the future? It would be useful if we have access to all
registered event listeners from context:

el.eventListeners << return some array

And we can loop through this array, get single event listener (read type,
callback, capture with the possibility of changes and one method to remove this
event listener totally).

If it is completely impossible maybe add to the EventTarget some method to
remove all event listeners. Now its not easy... especially when we have a lot
of them and some have anonymous callback. We must clone only context, move
content, and probably reconstruction some listeners (nothing pleasant).

I just wonder if there any chances of a better API for these things or we must
use some additional libraries/tricks.
