      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) => {

        } 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>

        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>

       This allows ember-testing to play nicely with other asynchronous
       events, such as an application that is waiting for a CSS3
       transition or an IndexDB transaction. The waiter runs periodically
       after each async helper (i.e. `click`, `andThen`, `visit`, etc) has executed,
       until the returning result is truthy. After the waiters finish, the next async helper
       is executed and the process repeats.
    
       For example:
    
       ```javascript
       import { registerWaiter } from '@ember/test';
    
       registerWaiter(function() {
         return myPendingTransactions() === 0;
       });
       ```
       The `context` argument allows you to optionally specify the `this`
       with which your callback will be invoked.
    
       For example:
    
       ```javascript
       import { registerWaiter } from '@ember/test';
    
       registerWaiter(MyDB, MyDB.hasPendingTransactions);

      `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 ];

      });
      ```
  
      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"
      });
      ```

      `Promise.race` returns a new promise which is settled in the same way as the

        // 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){

    /**
      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

      let result;
       try {
        result = findResult();

    /*
      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".
    
      😩😫🙀

      For non-focusable elements the following events are triggered (in order):
    
      - `mousedown`
