It only handles a special case, though, where one
branch is a strict postfix of another. It's no use
if the factoring you want to do is any more
complicated.

Also, it's backwards to require you to explicitly
state where you *don't* want fallthrough, when it's
most often not what you want.

I'm about -100 on fallthrough.
