-/**
- * DESIGN NOTES
- *
- * The design decisions behind the scope ware heavily favored for speed and memory consumption.
- *
- * The typical use of scope is to watch the expressions, which most of the time return the same
- * value as last time so we optimize the operation.
- *
- * Closures construction is expensive from speed as well as memory:
- *   - no closures, instead ups prototypical inheritance for API
- *   - Internal state needs to be stored on scope directly, which means that private state is
- *     exposed as $$____ properties
- *
- * Loop operations are optimized by using while(count--) { ... }
- *   - this means that in order to keep the same order of execution as addition we have to add
- *     items to the array at the begging (shift) instead of at the end (push)
- *
- * Child scopes are created and removed often
- *   - Using array would be slow since inserts in meddle are expensive so we use linked list
- *
- * There are few watches then a lot of observers. This is why you don't want the observer to be
- * implemented in the same way as watch. Watch requires return of initialization function which
- * are expensive to construct.

-     *
-     * @description
-     * A root scope can be retrieved using the {@link angular.module.ng.$rootScope $rootScope} key from the
-     * {@link angular.module.AUTO.$injector $injector}. Child scopes are created using the
-     * {@link angular.module.ng.$rootScope.Scope#$new $new()} method. (Most scopes are created automatically when
-     * compiled HTML template is executed.)
-     *
-     * Here is a simple scope snippet to show how you can interact with the scope.
-     * <pre>
-        angular.injector(['ng']).invoke(function($rootScope) {
-           var scope = $rootScope.$new();
-           scope.salutation = 'Hello';
-           scope.name = 'World';
-
-           expect(scope.greeting).toEqual(undefined);

-             this.greeting = this.salutation + ' ' + this.name + '!';
-           }); // initialize the watch
-
-           expect(scope.greeting).toEqual(undefined);
-           scope.name = 'Misko';
-           // still old value, since watches have not been called yet
-           expect(scope.greeting).toEqual(undefined);
-
-           scope.$digest(); // fire all  the watches
-           expect(scope.greeting).toEqual('Hello Misko!');
-        });
-     * </pre>
-     *
-     * # Inheritance
-     * A scope can inherit from a parent scope, as in this example:
-     * <pre>
-         var parent = $rootScope;
-         var child = parent.$new();
-
-         parent.salutation = "Hello";
-         child.name = "World";
-         expect(child.salutation).toEqual('Hello');
-
-         child.salutation = "Welcome";
-         expect(child.salutation).toEqual('Welcome');
-         expect(parent.salutation).toEqual('Hello');
-     * </pre>
-     *

-     * See {@link guide/dev_guide.di dependency injection}.
-     *

-     * @param {Object.<string, function()>=} providers Map of service factory which need to be provided
-     *     for the current scope. Defaults to {@link angular.module.ng}.

-     *     append/override services provided by `providers`. This is handy when unit-testing and having

-       * @function
-       *
-       * @description
-       * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
-       *
-       * - The `watchExpression` is called on every call to {@link angular.module.ng.$rootScope.Scope#$digest $digest()} and
-       *   should return the value which will be watched. (Since {@link angular.module.ng.$rootScope.Scope#$digest $digest()}
-       *   reruns when it detects changes the `watchExpression` can execute multiple times per
-       *   {@link angular.module.ng.$rootScope.Scope#$digest $digest()} and should be idempotent.)
-       * - The `listener` is called only when the value from the current `watchExpression` and the
-       *   previous call to `watchExpression' are not equal (with the exception of the initial run
-       *   see below). The inequality is determined according to
-       *   {@link angular.equals} function. To save the value of the object for later comparison
-       *   {@link angular.copy} function is used. It also means that watching complex options will
-       *   have adverse memory and performance implications.
-       * - The watch `listener` may change the model, which may trigger other `listener`s to fire. This
-       *   is achieved by rerunning the watchers until no changes are detected. The rerun iteration
-       *   limit is 100 to prevent infinity loop deadlock.
-       *
-       *
-       * If you want to be notified whenever {@link angular.module.ng.$rootScope.Scope#$digest $digest} is called,
-       * you can register an `watchExpression` function with no `listener`. (Since `watchExpression`,
-       * can execute multiple times per {@link angular.module.ng.$rootScope.Scope#$digest $digest} cycle when a change is
-       * detected, be prepared for multiple calls to your listener.)
-       *
-       * After a watcher is registered with the scope, the `listener` fn is called asynchronously
-       * (via {@link angular.module.ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
-       * watcher. In rare cases, this is undesirable because the listener is called when the result
-       * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
-       * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
-       * listener was called due to initialization.
-       *
-       *
