Thanks for the input. Many (but not all) of those have some amount of dependency upon i109. I've been writing a straw-man proposal for it in the background, and should post it soon (please don't let that stop you if you have ideas). I don't know that I agree we'll have to declae so many implementations as wrong, but let's see where we go.
