    Allows for runtime registration of handler functions that override the default deprecation behavior.
    Deprecations are invoked by calls to [@ember/debug/deprecate](/ember/release/classes/@ember%2Fdebug/methods/deprecate?anchor=deprecate).
    The following example demonstrates its usage by registering a handler that throws an error if the
    message contains the word "should", otherwise defers to the default handler.
  
    ```javascript
    import { registerDeprecationHandler } from '@ember/debug';
  
    registerDeprecationHandler((message, options, next) => {
      if (message.indexOf('should') !== -1) {
        throw new Error(`Deprecation message with should: ${message}`);
      } else {
        // defer to whatever handler was registered before this one
        next(message, options);
      }
    });
    ```
  
    The handler function takes the following arguments:
  
    <ul>
      <li> <code>message</code> - The message received from the deprecation call.</li>
      <li> <code>options</code> - An object passed in with the deprecation call containing additional information including:</li>
        <ul>
          <li> <code>id</code> - An id of the deprecation in the form of <code>package-name.specific-deprecation</code>.</li>
          <li> <code>until</code> - The Ember version number the feature and deprecation will be removed in.</li>
        </ul>
      <li> <code>next</code> - A function that calls into the previously registered handler.</li>
    </ul>

      Allows for runtime registration of handler functions that override the default warning behavior.
      Warnings are invoked by calls made to [@ember/debug/warn](/ember/release/classes/@ember%2Fdebug/methods/warn?anchor=warn).
      The following example demonstrates its usage by registering a handler that does nothing overriding Ember's
      default warning behavior.
         ```javascript
      import { registerWarnHandler } from '@ember/debug';
         // next is not called, so no warnings get the default behavior
      registerWarnHandler(() => {});
      ```
         The handler function takes the following arguments:
         <ul>
        <li> <code>message</code> - The message received from the warn call. </li>
        <li> <code>options</code> - An object passed in with the warn call containing additional information including:</li>
          <ul>
            <li> <code>id</code> - An id of the warning in the form of <code>package-name.specific-warning</code>.</li>
          </ul>
        <li> <code>next</code> - A function that calls into the previously registered handler.</li>

    `registerHelper` is used to register a test helper that will be injected
    when `App.injectTestHelpers` is called.
  
    The helper method will always be called with the current Application as

    For example:

    registerHelper('boot', function(app) {

    This helper can later be called without arguments because it will be
    called with `app` as the first parameter.
  
    ```javascript
    import Application from '@ember/application';
  
    App = Application.create();

    `Promise.all` accepts an array of promises, and returns a new promise which
    is fulfilled with an array of fulfillment values for the passed promises, or
    rejected with the reason of the first passed promise to be rejected. It casts all
    elements of the passed iterable to promises as it runs this algorithm.

    Example:

    ```javascript
    let promise1 = resolve(1);
    let promise2 = resolve(2);
    let promise3 = resolve(3);
    let promises = [ promise1, promise2, promise3 ];

    Promise.all(promises).then(function(array){
      // The array here would be [ 1, 2, 3 ];
    });
    ```

    If any of the `promises` given to `all` are rejected, the first promise
    that is rejected will be given as an argument to the returned promises's
    rejection handler. For example:

    Example:

    ```javascript
    let promise1 = resolve(1);
    let promise2 = reject(new Error("2"));
    let promise3 = reject(new Error("3"));
    let promises = [ promise1, promise2, promise3 ];

    Promise.all(promises).then(function(array){
      // Code here never runs because there are rejected promises!
    }, function(error) {
      // error.message === "2"
    });
    ```

    @method all
    @static
    @param {Array} entries array of promises
    @param {String} label optional string for labeling the promise.
    Useful for tooling.
    @return {Promise} promise that is fulfilled when all `promises` have been
    fulfilled, or rejected if any of them become rejected.
    @static
  */
  function all(entries) {
    return new Enumerator(this, entries).promise;
  }

  /**
    `Promise.race` returns a new promise which is settled in the same way as the
    first passed promise to settle.

    Example:

    ```javascript
    let promise1 = new Promise(function(resolve, reject){
      setTimeout(function(){
        resolve('promise 1');
      }, 200);
    });

    let promise2 = new Promise(function(resolve, reject){
      setTimeout(function(){
        resolve('promise 2');
      }, 100);
    });

    Promise.race([promise1, promise2]).then(function(result){
      // result === 'promise 2' because it was resolved before promise1
      // was resolved.
    });
    ```

    `Promise.race` is deterministic in that only the state of the first
    settled promise matters. For example, even if other promises given to the
    `promises` array argument are resolved, but the first settled promise has
    become rejected before the other promises became fulfilled, the returned
    promise will become rejected:

    ```javascript
    let promise1 = new Promise(function(resolve, reject){
      setTimeout(function(){
        resolve('promise 1');
      }, 200);
    });

    let promise2 = new Promise(function(resolve, reject){
      setTimeout(function(){
        reject(new Error('promise 2'));
      }, 100);
    });

    Promise.race([promise1, promise2]).then(function(result){
      // Code here never runs
    }, function(reason){
      // reason.message === 'promise 2' because promise 2 became rejected before
      // promise 1 became fulfilled
    });
    ```

    An example real-world use case is implementing timeouts:

    ```javascript
    Promise.race([ajax('foo.json'), timeout(5000)])
    ```

    @method race
    @static

    Useful for tooling.
    @return {Promise} a promise which settles in the same way as the first passed
    promise to settle.

  /**
    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
    let 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){
        let 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
  */

  var Promise$2 = function () {
    function Promise(resolver) {
      classCallCheck(this, Promise);

      this[PROMISE_ID] = nextId();
      this._result = this._state = undefined;
      this._subscribers = [];

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

    /**
    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
    --------------
     Synchronous Example
     ```javascript
    let result;
     try {
      result = findResult();
      // success
    } catch(reason) {
      // failure
    }
    ```
     Errback Example
     ```js
    findResult(function(result, err){
      if (err) {
        // failure
      } else {
        // success
      }
    });
    ```
     Promise Example;

      // success
    }, function(reason){
      // failure

  /*
    Long ago in a galaxy far far away, Ember forced RSVP.Promise to "resolve" on the Ember.run loop.
    At the time, this was meant to help ease pain with folks receiving the dreaded "auto-run" assertion
    during their tests, and to help ensure that promise resolution was coelesced to avoid "thrashing"
    of the DOM. Unfortunately, the result of this configuration is that code like the following behaves
    differently if using native `Promise` vs `RSVP.Promise`:
  
    ```js
    console.log('first');
    Ember.run(() => Promise.resolve().then(() => console.log('second')));
    console.log('third');
    ```
  
    When `Promise` is the native promise that will log `'first', 'third', 'second'`, but when `Promise`
    is an `RSVP.Promise` that will log `'first', 'second', 'third'`. The fact that `RSVP.Promise`s can
    be **forced** to flush synchronously is very scary!
  
    Now, lets talk about why we are configuring `RSVP`'s `async` below...
  
    ---
  
    The following _should_ always be guaranteed:
  
    ```js
    await settled();
  
    isSettled() === true
    ```
  
    Unfortunately, without the custom `RSVP` `async` configuration we cannot ensure that `isSettled()` will
    be truthy. This is due to the fact that Ember has configured `RSVP` to resolve all promises in the run
    loop. What that means practically is this:
  
    1. all checks within `waitUntil` (used by `settled()` internally) are completed and we are "settled"
    2. `waitUntil` resolves the promise that it returned (to signify that the world is "settled")
    3. resolving the promise (since it is an `RSVP.Promise` and Ember has configured RSVP.Promise) creates
      a new Ember.run loop in order to resolve
    4. the presence of that new run loop means that we are no longer "settled"
    5. `isSettled()` returns false 😭😭😭😭😭😭😭😭😭
  
    This custom `RSVP.configure('async`, ...)` below provides a way to prevent the promises that are returned
    from `settled` from causing this "loop" and instead "just use normal Promise semantics".
  
    😩😫🙀

   * you must pass the `options` param as an object with a key of `dataTransfer`. The `options.dataTransfer`     object should have a `files` key, containing an array of [File](https://developer.mozilla.org/en-US/docs/Web/API/File).
