Previously the arguments were the namespace(s) and the type. That's nice and simple. Now it's the first namespace, and then all the other namespaces and the type. That's not very clean. There must be a way to keep the add_version and add_container calls the same, and have it transparently handle the case where the namespace is 'std::__8::foo' not 'std::foo'.
