Re: [whatwg/xhr] Abandon hope of removing sync XHR from the web platform? (#20)

Someone brought up an interesting use case to me: recursion.

Isn't synchronicity required for recursion? If you're doing a Fibonacci sequence via ajax requests, you NEED to wait on the reply of f(1) to get f(2). Or am I missing something? Maybe I should try it as an exercise in crazy.

Of course, I don't know of anyone who's doing this - why would you do recursive ajax requests that sounds terrible - but it's technically a reason you shouldn't drop support - because there'd be no other way to do that, right?
