      Promise objects represent the eventual result of an asynchronous operation. The
      primary way of interacting with a promise is through its `then` method, which
      registers callbacks to receive either a promise's eventual value or the reason
      why the promise cannot be fulfilled.

      Terminology
      -----------

      - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
      - `thenable` is an object or function that defines a `then` method.
      - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
      - `exception` is a value that is thrown using the throw statement.
      - `reason` is a value that indicates why a promise was rejected.
      - `settled` the final resting state of a promise, fulfilled or rejected.

      A promise can be in one of three states: pending, fulfilled, or rejected.

      Promises that are fulfilled have a fulfillment value and are in the fulfilled
      state.  Promises that are rejected have a rejection reason and are in the
      rejected state.  A fulfillment value is never a thenable.

      Promises can also be said to *resolve* a value.  If this value is also a
      promise, then the original promise's settled state will match the value's
      settled state.  So a promise that *resolves* a promise that rejects will
      itself reject, and a promise that *resolves* a promise that fulfills will
      itself fulfill.


      Basic Usage:
      ------------

      ```js
      var promise = new Promise(function(resolve, reject) {
        // on success
        resolve(value);

        // on failure
        reject(reason);
      });

      promise.then(function(value) {
        // on fulfillment
      }, function(reason) {
        // on rejection
      });
      ```

      Advanced Usage:
      ---------------

      Promises shine when abstracting away asynchronous interactions such as
      `XMLHttpRequest`s.

      ```js
      function getJSON(url) {
        return new Promise(function(resolve, reject){
          var xhr = new XMLHttpRequest();

          xhr.open('GET', url);
          xhr.onreadystatechange = handler;
          xhr.responseType = 'json';
          xhr.setRequestHeader('Accept', 'application/json');
          xhr.send();

          function handler() {
            if (this.readyState === this.DONE) {
              if (this.status === 200) {
                resolve(this.response);
              } else {
                reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
              }
            }
          };
        });
      }

      getJSON('/posts.json').then(function(json) {
        // on fulfillment
      }, function(reason) {
        // on rejection
      });
      ```

      Unlike callbacks, promises are great composable primitives.

      ```js
      Promise.all([
        getJSON('/posts'),
        getJSON('/comments')
      ]).then(function(values){
        values[0] // => postsJSON
        values[1] // => commentsJSON

        return values;
      });
      ```

      @class Promise
      @param {function} resolver
      Useful for tooling.
      @constructor
    */
    function lib$es6$promise$promise$$Promise(resolver) {
      this[lib$es6$promise$$internal$$PROMISE_ID] = lib$es6$promise$$internal$$nextId();
      this._result = this._state = undefined;
      this._subscribers = [];

      if (lib$es6$promise$$internal$$noop !== resolver) {
        typeof resolver !== 'function' && lib$es6$promise$promise$$needsResolver();
        this instanceof lib$es6$promise$promise$$Promise ? lib$es6$promise$$internal$$initializePromise(this, resolver) : lib$es6$promise$promise$$needsNew();
      }
    }

    lib$es6$promise$promise$$Promise.all = lib$es6$promise$promise$all$$default;
    lib$es6$promise$promise$$Promise.race = lib$es6$promise$promise$race$$default;
    lib$es6$promise$promise$$Promise.resolve = lib$es6$promise$promise$resolve$$default;

    lib$es6$promise$promise$$Promise._asap = lib$es6$promise$asap$$asap;

    lib$es6$promise$promise$$Promise.prototype = {
      constructor: lib$es6$promise$promise$$Promise,

    /**
      The primary way of interacting with a promise is through its `then` method,
      which registers callbacks to receive either a promise's eventual value or the
      reason why the promise cannot be fulfilled.

      ```js
      findUser().then(function(user){
        // user is available
      }, function(reason){
        // user is unavailable, and you are given the reason why
      });
      ```

      Chaining
      --------

      The return value of `then` is itself a promise.  This second, 'downstream'
      promise is resolved with the return value of the first promise's fulfillment
      or rejection handler, or rejected if the handler throws an exception.

      ```js
      findUser().then(function (user) {
        return user.name;
      }, function (reason) {
        return 'default name';
      }).then(function (userName) {
        // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
        // will be `'default name'`
      });

      findUser().then(function (user) {
        throw new Error('Found user, but still unhappy');
      }, function (reason) {
        throw new Error('`findUser` rejected and we're unhappy');
      }).then(function (value) {
        // never reached
      }, function (reason) {
        // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
        // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
      });
      ```
      If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.

      ```js
      findUser().then(function (user) {
        throw new PedagogicalException('Upstream error');
      }).then(function (value) {
        // never reached
      }).then(function (value) {
        // never reached
      }, function (reason) {
        // The `PedgagocialException` is propagated all the way down to here
      });
      ```

      Assimilation
      ------------

      Sometimes the value you want to propagate to a downstream promise can only be
      retrieved asynchronously. This can be achieved by returning a promise in the
      fulfillment or rejection handler. The downstream promise will then be pending
      until the returned promise is settled. This is called *assimilation*.

      ```js
      findUser().then(function (user) {
        return findCommentsByAuthor(user);
      }).then(function (comments) {
        // The user's comments are now available
      });
      ```

      If the assimliated promise rejects, then the downstream promise will also reject.

      ```js
      findUser().then(function (user) {
        return findCommentsByAuthor(user);
      }).then(function (comments) {
        // If `findCommentsByAuthor` fulfills, we'll have the value here
      }, function (reason) {
        // If `findCommentsByAuthor` rejects, we'll have the reason here
      });
      ```

      Simple Example
      --------------

      try {
        result = findResult();
