Hmm, so it's not the case that @before methods are
called "before" all other methods. That makes it even
more confusing.

I'm now even more of the opinion that this is too
complicated for Python's first generic function system.
"If it's hard to explain, it's probably a bad idea."

Relying on people knowing about CLOS in order to follow
this stuff doesn't seem like a good idea.
