$return->build() and $result->build() replaced by:

```php
    $vars = Router::getControllerVars();
    if( isset( $this->params['controller_method'] ) ) {
        $method = $this->params['controller_method'];
    } else {
        $method = 'build';
    }
    $return = call_user_func_array (array( $this, $method ) , $vars );
```
