ÂMe gusta mucho! This system allows neato things like anonymous namespaces, too. I was thinking of something similar for classes. An object holds a reference to a class PMC which is used to fetch its methods. This allows different metaclasses (which are, again, required for Perl 6[1]). Maybe said class PMC is, by default, just an anonymous namespace PMC. Luke
