<div>The code as written is correct. The rewritten version would actually just emit [someView.superview, someView.superview, someView.superview, ...] forever. I imagine the confusion stems from the fact that there's 2 examples but they both demonstrate just the first function, and there's no examples of the second function, which is something I'll try to address soon.<br></div>
