A. reminds me of JS objects. B. is to expected, and I think it might be useful; e.g. we prevent accidental copying of singletons in C++ via operator= (T &other) = delete;. I'd guess you could do something similar in python. To top that: Yesterday I learned that you can legally overload the unary operator & in C++. Smuggling that into a large code base seems like a good way to mess with your colleagues ;)
