Variadic grouping

Man I love it when this Javascript bloke posts. The tantrums are 
brilliant :-)

JS: Why does D not do X, it should and without it D is useless. 
Implement my minions!
DD: Why should X be implemented? Show us some example where it 
would be useful.
JS: You are an ignorant stupid fool if you cannot see the 
benefit. And obviously too lazy to figure out an example yourself.

Here's your dummy JS, but please keep spitting it. It gives me 
great amusement reading your posts when you've been on the bean.
