// This event emitter emits events, but reserves the right to publish events to
// for its creator. It uses a WeakMap for true encapsulation.

const eesToEventMaps = new WeakMap();

export default class EventEmitter {
    constructor(publisher) {
        const eventMap = Object.create(null);
        eesToEventMaps.set(this, eventMap);
