    /**
      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 RSVP.Promise
      @param {function} resolver
      @param {String} label optional string for labeling the promise.
      Useful for tooling.
      @constructor
    */
    function $$rsvp$promise$$Promise(resolver, label) {
      this._id = $$rsvp$promise$$counter++;
      this._label = label;
      this._state = undefined;
      this._result = undefined;
      this._subscribers = [];

      if ($$rsvp$config$$config.instrument) {
        $$instrument$$default('created', this);
      }

      if ($$$internal$$noop !== resolver) {
        if (!$$utils$$isFunction(resolver)) {
          $$rsvp$promise$$needsResolver();
        }

        if (!(this instanceof $$rsvp$promise$$Promise)) {
          $$rsvp$promise$$needsNew();
        }

        $$$internal$$initializePromise(this, resolver);
      }
    }

    // deprecated
    $$rsvp$promise$$Promise.cast = $$promise$resolve$$default;

    $$rsvp$promise$$Promise.all = $$promise$all$$default;
    $$rsvp$promise$$Promise.race = $$promise$race$$default;
    $$rsvp$promise$$Promise.resolve = $$promise$resolve$$default;
    $$rsvp$promise$$Promise.reject = $$promise$reject$$default;

    $$rsvp$promise$$Promise.prototype = {
      constructor: $$rsvp$promise$$Promise,

      _guidKey: $$rsvp$promise$$guidKey,

      _onerror: function (reason) {
        $$rsvp$config$$config.trigger('error', reason);
      },

    /**
      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
      });
      ```

      try {
        result = findResult();

The\n      primary way of interacting with a promise is through its `then` method, which\n      registers callbacks to receive either a promise’s eventual value or the reason\n      why the promise cannot be fulfilled.\n\n      Terminology\n      -----------\n\n      - `promise` is an object or function with a `then` method whose behavior conforms to this specification.\n      - `thenable` is an object or function that defines a `then` method.\n      - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).\n      - `exception` is a value that is thrown using the throw statement.\n      - `reason` is a value that indicates why a promise was rejected.\n      - `settled` the final resting state of a promise, fulfilled or rejected.\n\n      A promise can be in one of three states: pending, fulfilled, or rejected.\n\n      Promises that are fulfilled have a fulfillment value and are in the fulfilled\n      state.  Promises that are rejected have a rejection reason and are in the\n      rejected state.  A fulfillment value is never a thenable.\n\n      Promises can also be said to *resolve* a value.  If this value is also a\n      promise, then the original promise's settled state will match the value's\n      settled state.  So a promise that *resolves* a promise that rejects will\n      itself reject, and a promise that *resolves* a promise that fulfills will\n      itself fulfill.\n\n\n      Basic Usage:\n      ------------\n\n      ```js\n      var promise = new Promise(function(resolve, reject) {\n        // on success\n        resolve(value);\n\n        // on failure\n        reject(reason);\n      });\n\n      promise.then(function(value) {\n        // on fulfillment\n      }, function(reason) {\n        // on rejection\n      });\n      ```\n\n      Advanced Usage:\n      ---------------\n\n      Promises shine when abstracting away asynchronous interactions such as\n      `XMLHttpRequest`s.\n\n      ```js\n      function getJSON(url) {\n        return new Promise(function(resolve, reject){\n          var xhr = new XMLHttpRequest();\n\n          xhr.open('GET', url);\n          xhr.onreadystatechange = handler;\n          xhr.responseType = 'json';\n          xhr.setRequestHeader('Accept', 'application/json');\n          xhr.send();\n\n          function handler() {\n            if (this.readyState === this.DONE) {\n              if (this.status === 200) {\n                resolve(this.response);\n              } else {\n                reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));\n              }\n            }\n          };\n        });\n      }\n\n      getJSON('/posts.json').then(function(json) {\n        // on fulfillment\n      }, function(reason) {\n        // on rejection\n      });\n      ```\n\n      Unlike callbacks, promises are great composable primitives.\n\n      ```js\n      Promise.all([\n        getJSON('/posts'),\n        getJSON('/comments')\n      ]).then(function(values){\n        values[0] // => postsJSON\n        values[1] // => commentsJSON\n\n        return values;\n      });\n      ```\n\n      @class RSVP.Promise\n      @param {function} resolver\n      @param {String} label optional string for labeling the promise.\n      Useful for tooling.\n      @constructor\n    */\n    function $$rsvp$promise$$Promise(resolver, label) {\n      this._id = $$rsvp$promise$$counter++;\n      this._label = label;\n      this._state = undefined;\n      this._result = undefined;\n      this._subscribers = [];\n\n      if ($$rsvp$config$$config.instrument) {\n        $$instrument$$default('created', this);\n      }\n\n      if ($$$internal$$noop !== resolver) {\n        if (!$$utils$$isFunction(resolver)) {\n          $$rsvp$promise$$needsResolver();\n        }\n\n        if (!(this instanceof $$rsvp$promise$$Promise)) {\n          $$rsvp$promise$$needsNew();\n        }\n\n        $$$internal$$initializePromise(this, resolver);\n      }\n    }\n\n    // deprecated\n    $$rsvp$promise$$Promise.cast = $$promise$resolve$$default;\n\n    $$rsvp$promise$$Promise.all = $$promise$all$$default;\n    $$rsvp$promise$$Promise.race = $$promise$race$$default;\n    $$rsvp$promise$$Promise.resolve = $$promise$resolve$$default;\n    $$rsvp$promise$$Promise.reject = $$promise$reject$$default;\n\n    $$rsvp$promise$$Promise.prototype = {\n      constructor: $$rsvp$promise$$Promise,\n\n      _guidKey: $$rsvp$promise$$guidKey,\n\n      _onerror: function (reason) {\n        $$rsvp$config$$config.trigger('error', reason);\n      },\n\n    /**\n      The primary way of interacting with a promise is through its `then` method,\n      which registers callbacks to receive either a promise's eventual value or the\n      reason why the promise cannot be fulfilled.\n\n      ```js\n      findUser().then(function(user){\n        // user is available\n      }, function(reason){\n        // user is unavailable, and you are given the reason why\n      });\n      ```\n\n      Chaining\n      --------\n\n      The return value of `then` is itself a promise.  This second, 'downstream'\n      promise is resolved with the return value of the first promise's fulfillment\n      or rejection handler, or rejected if the handler throws an exception.\n\n      ```js\n      findUser().then(function (user) {\n        return user.name;\n      }, function (reason) {\n        return 'default name';\n      }).then(function (userName) {\n        // If `findUser` fulfilled, `userName` will be the user's name, otherwise it\n        // will be `'default name'`\n      });\n\n      findUser().then(function (user) {\n        throw new Error('Found user, but still unhappy');\n      }, function (reason) {\n        throw new Error('`findUser` rejected and we're unhappy');\n      }).then(function (value) {\n        // never reached\n      }, function (reason) {\n        // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.\n        // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.\n      });\n      ```\n      If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.\n\n      ```js\n      findUser().then(function (user) {\n        throw new PedagogicalException('Upstream error');\n      }).then(function (value) {\n        // never reached\n      }).then(function (value) {\n        // never reached\n      }, function (reason) {\n        // The `PedgagocialException` is propagated all the way down to here\n      });\n      ```\n\n      Assimilation\n      ------------\n\n      Sometimes the value you want to propagate to a downstream promise can only be\n      retrieved asynchronously. This can be achieved by returning a promise in the\n      fulfillment or rejection handler. The downstream promise will then be pending\n      until the returned promise is settled. This is called *assimilation*.\n\n      ```js\n      findUser().then(function (user) {\n        return findCommentsByAuthor(user);\n      }).then(function (comments) {\n        // The user's comments are now available\n      });\n      ```\n\n      If the assimliated promise rejects, then the downstream promise will also reject.\n\n      ```js\n      findUser().then(function (user) {\n        return findCommentsByAuthor(user);\n      }).then(function (comments) {\n        // If `findCommentsByAuthor` fulfills, we'll have the value here\n      }, function (reason) {\n        // If `findCommentsByAuthor` rejects, we'll have the reason here\n      });\n      ```\n\n      Simple Example\n      --------------\n\n      Synchronous Example\n\n      ```javascript\n      var result;\n\n      try {\n        result = findResult();\n        // success\n      } catch(reason) {\n        // failure\n      }\n      ```\n\n      Errback Example\n\n      ```js\n
