But I don't think people that *really* need to be in full control would
see a RC GC as something tempting. As long as there is an option to
(easily) avoid the GC, I'm happy, if you want to provice an RC
implementation then, great. I can't see an RC implementation fitting very
well in D (because of slicing and other features, mostly the very same
features that makes the D GC very conservative and inefficient).
