OO methodologies provide criteria for choosing between
different designs, but as we've brought out here, a good OO design *hides*
My impression is that some OO practitioners woud rather say "encapsulate"
than "hide". But that still begs the question of how to expose the structure
(at the risk of re-kindling a dying ember).
