How to define $this variable for phpstorm to autocomplete?
Code example

$app->get( '/auth/:action', function( $action ) {
        // $this === $app
        /** @var $this App */
        return $this->view->render( "auth.php" );
} );

/** @var $this App */- I know this method, but is it possible to somehow do without it?
use ( $app )also not an option.
Thank you!

You don't need to name the variable by that name. This will confuse people.
