[issue19002] ``dir`` function does not work correctly with classes.

It's going to take more than "I think that that's not true," to get a change made.

Currently, `dir(cls)` returns information that tells us how instances of that class will behave.  Because metaclass methods have no direct effect on instance behavior, having dir return metaclass methods and attributes would be confusing.

If you want to know how a class is going to behave you need to `dir(cls.__class__)`.
