some kind of interaction with templates, RefCounted, and the

Actually, both of your examples compile for me - both with master 
and with 2.070.0. I'm running on x86_64 FreeBSD (which you 
probably aren't), which shouldn't matter for this sort of error, 
but I suppose that it's possible that it's somehow 
system-specific, much as I wouldn't expect it to be. So, I don't 
what to say. :|
