Well, in the general case I wouldn't quarrel. Just, absolute rules are
a Bad Thing, and there should always be a waiver mechanism!
In the BC.Graph case, it's clear that Graph, Arc and Vertex are
different things that must cooperate intimately to achieve the
purpose. I don't propose to second-guess Grady on this design. Just
one point -- in this case, of course child packages wouldn't be the
logical answer, because the behaviours of the three types are very
different.
