Oh!  That does make it simpler, and would seem to eliminate Joe's 
objection regarding RMS' extensions.

IMO, if these are C++-only, it's relatively easy to deprecate these 
extension -- but I'd like to hear from Jason and Nathan, and also the 
user community before we do that.  Of all the extensions we've had, this 
one really hasn't been that problematic.

Indeed.
