singleton using metaclass

[bb8]

i don't quite well understand how could that work. what if i want the class to have methods?

I think your question is not at all about singletons. I don't see the problem with defining a class with methods, properties, etc and the create a single instance. Why would there be a problem?

because you wrote the class name and "pass". where would i decalre the methods?
