Come up with a good design for Event handling

[renatoathaydes]

EvenHandling can probably benefit from Ceylon's syntax, similarly to Bindings as on #2.

Eliminate ActionListener interfaces and just use Callables directly? Like this:

interface ActionListener => Anything(ActionEvent);

closeButton.setOnAction(void (ActionEvent event) {
    print("Bye!");
    process.exit(0);
});

+1.

Yes, I agree... creating event handlers inside node declarations should also be straight-forward...

Button {
    onAction = (ActionEvent event) => print(event);
}

yes, that also looks very nice. what should be the default value in the constructor – noop() or null?

I've been making this kind of thing null... it's not shared and the only time I need to check it for existence is when creating the component, simple enough.
