Description
Wrapped values are unwrapped automatically during the change detection, and the unwrapped value is stored.
Example:
if (this._latestValue === this._latestReturnedValue) {
return this._latestReturnedValue;
} else {
this._latestReturnedValue = this._latestValue;
return WrappedValue.wrap(this._latestValue); // this will force update
}
