This comment is ironic since changing a preference value isn't really something
we can do (you lose the old value, right?). But it's fine to leave it.

Also this could probably just live right above the namespace prefs { line? But
either way.

Haha, you make a great point about them not really being change-able. I'm just
going to remove this comment, it's not really adding value.
