Not easy to read is it? I can't require that users of my applications
extend it using code like the above, they aren't experienced
programmers. Isn't the code bellow much easier to understand?

class TextButton extends Button -- or TextButton = class(Button) ... end
	local text

	constructor init(aText)
		text = aText
	end

	function draw(g)
		inherited draw(g)
		...
	end
end

b = new Button.init('Click me!') -- or some similar syntax
