const em = emitter();
const proxyFactory = proxyListener({MY_EVENT:'myMethod'});
const instance = proxyFactory({emitter:em);

const listener = (...args) => console.log(args);

//register with convenient method
instance.myMethod(listener);

em.dispatch('MY_EVENT','foo','bar');
// > ['foo','bar']

//unsubscribe
instance.off('MY_EVENT') //unregister all listeners to MY_EVENT held by the proxy instance
instance.off() //unregister all listeners held by the proxy instance
