I'm not the smartest guy ever, but I had trouble understanding this example and had to read the tests to see what's going on.

I think part of the problem is that you're still initializing with .new; it'd be clearer with a different method.

Also, maybe you could include a line or two about why you'd want this. I'm having trouble picturing when I'd use this.
