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.
