          This method constructs an event object and then passes it to :meth:`dispatch_event` for
          the actual dispatching.
  
          :param args: positional arguments to the constructor of the associated event class
          :param kwargs: keyword arguments to the constructor of the associated event class
          :returns: an awaitable that completes when all the callbacks have been called (and any
              awaitables waited on) and resolves to ``True`` if there were no exceptions raised by
              the callbacks, ``False`` otherwise
