  Indicates that the result of a <a href='../annotations/Pipe-var.html'><code>Pipe</code></a> transformation has changed even though the reference
  has not changed.
  
  The wrapped value will be unwrapped by change detection, and the unwrapped value will be stored.
  
  Example:
  
  ```
  if (this._latestValue === this._latestReturnedValue) {
     return this._latestReturnedValue;
   } else {
     this._latestReturnedValue = this._latestValue;
     return WrappedValue.wrap(this._latestValue); // this will force update
   }
  ```
