Does Andreas refer here to something that is implemented, or just that
I'm abusing the concept Listener?
If the latter, what do you think about creating an explicit group for
filters, using a separate
dispatcher method? [1]
Or is there a much better place for intercepting events?

Thanks, Balázs

[1] E.g create eventFilters ivar and accessors analog to
eventListeners ivar and accessors,
and #sendFilterEvent:to method analog to #sendListenEvent:to.
