Heh, I'm not totally surprised -- I took Python's metaclass design from a book named Putting Metaclasses to Work, by Ira R. Forman and Scott H. Danforth ( https://www.amazon.com/Putting-Metaclasses-Work-Ira-Forman/dp/0201433052). The book describes a custom metaclass extension to C++ supporting metaclasses, from which I took everything I could given that Python is a dynamic language (the key thing I left out was automatic synthesis of combined metaclasses when multiple inheritance sees two unrelated metaclasses). Hopefully the authors get some credit in the current C++ standard proposal.
