How to determine if object has a defined event

Is there a way to determine if an object instance imlements an event like ismethod for methods and isprop for properties?

I tried isevent but it seems to be related only to COM components

I know I can use metaclass but it's much more tedious

and i don't mean something like that:

try
    addlistener(whatever goes here);
catch ME
    % no such event
end

Best method I found was

ismember('EventName', events(obj));
