Can you explain the use of "yield" in that code, or link to something that explains it? This doesn't look like a generator. I don't think I've seen the value of a yield expression assigned to a local before.
It's a Tornado thing. It's awesome because it's an alternative to using callbacks basically. Unlike callbacks which need a new function/method with new parameters and scope, this method just carries on on the next line like any procedural program. I was turned on by Tornado before this was added and now it just makes it even sexier.
