Sorry again, Mark.

On reflection it's not at all clear whether we should get rid of this
bizarrity for all α-methods, or just for β-methods. It would be easy
enough to word things either way, I think. On balance I'm inclined to
believe it better to just make it go away for β-methods and still allow
it for α-methods. If others actually have any opinions on this,
perhaps it, too, is worthy of a poll eventually, though I suggest +not+
doing so until after we've made more progress on the stuff of wider
interest.
