You can, sort of. However, I don't get the current mania for appending
methods to the class-object and the instance-object at the same time.

When I started with Ruby, people weren't doing things that way and
weren't looking for ways to do it that way.

What people are doing is trying to get MI out of mixins, and they're not
that.
