Types really only help when they're primitives. You're going to have a million random classes that are only used in a few places. Seeing `ConfigManagerFactory config_manager_factory` doesn't help. What helps is avoiding excessive oop and making sure objects are printable for debug, imo something Javascript does a lot better.

Re null pointers, in Java or Python they raise an exception. Isn't that ok? It doesn't end up doing something invalid like in C.
