Yes, please do!  If we can push this through, D could be in a much, much
better place in a few years' time!

Actually, couldn't we use the same versioning mechanism for *most* of
the proposed changes that are currently turned down because they would
break too much code? Using this versioning would allow us to introduce
breaking changes in an opt-in way, thus allowing codebases the needed
time to migrate.
