Have you ever come across an appropriate usage of the 'sealed' keyword (on a class or a method)? I understand what it does but I can't imagine where it's really useful. I've heard it speeds up an application a little bit (since the interpreter doesn't have to look for children classes or something like that), but is it worth it to seal classes only because of that?
