I see this has been integrated but I have concerns that the use-sites now all 
assume that the package name has been intern'ed. We may some crumbs, maybe in 
an implNote or comment in the Class::getPackageName code, otherwise we risk 
breakage if getPackageName changed to return a non-intern'ed string at some 
point.
