Generally speaking I agree with you and Kazuho, as we can see based on the way I implemented the priority mechanic in code. ;)

However, Martin edited the spec and proposed the erratum, so his understanding of the specification does carry a decent chunk of weight. That’s why I asked implementers to chime in: right now we appear to have Martin on one side, and three implementations on the other.

For now I’m mostly interested to see if Martin (or anyone else who agrees with Martin) can chime in on that position.
