Return types in API documentation would be valuable

Unless I'm missing it, I'm not really seeing return types as part of the API documentation.

For example, if you go here:

https://docs.phalcon.io/en/latest/api/Phalcon_Application.html

You will see that there is a method called handle(). However, it does not showcase the return type, which does exist. This causes confusion when developers are trying to understand how code like this might work:

    $application = new Application($di);
    $response = $application->handle();
    $response->send();
