On a related note, where can we find the latest documentation for the Dispatch overlay? The Apple docs don’t have any actual usage information yet, so is there any documentation actually generated from code, like swiftdoc.org does for the standard library?

Isn't `serial` the default? If so, you should just be able to pass an empty array literal (`[]`) or omit the `attributes` parameter entirely.
