Yes, that looks interesting, but I think it has a couple of drawbacks.
First, it requires another completely separate class for the
"implementation" (although perhaps that could be a nested class).
Secondly, I think it essentially just adds a sort of inner namespace
through which the "private" data is accessed. That might be a good
idea, but I don't think it's quite the same as encapsulation.
