It works with objects inheriting from Object.prototype and which do not have an own 'on' property (which would shadow yours) or an own 'event' property (because you create one). As I stated in my initial e-mail, my goal was to support having the ability to list events in order to potentially have doc and IDE support or at least analysis. I agree that you could easily support enumeration of events (with the getOwnPropertyNames trap for your "event" property), but it would require actually running the code (JavaScript static analysis or rather abstract interpretation is very hard, but I haven't even started to think about how proxies makes this even harder!) Unlike if you can just (semi-)syntactically declare that your property is an event with the event attribute of the property descriptor or with an addition to the object literal syntax as Erik suggested.
