EventHandler::AnyEvent::Channel

Meta event, emitted on every other event. Adding a handler for this event allows listening for all emitted events and their arguments.

Not emitted for the AddHandlerEvent/RemoveHandlerEvent the shard itself raises on on/off (those are dispatched to their own handlers only; one emitted explicitly with emit is an ordinary event and does reach AnyEvent handlers), nor for an AnyEvent emitted directly.
