class FooBar which is damn cool
    and extends Foo
    and implements Bar, Baz.
It does many things right. 'nuff said.

FooBar's elements:
    method doSomething which does something
        has parameters
            value which is funny
        does
            var tmp := value;
            return tmp;

Cool, eh?

Yeah, that's it!
