Thanks for the explanation - I think that makes sense, that node printability is an orthogonal concept from the graph traits, hopefully. (the counterexample to this would be if two graphs have the same noderef type but need different printing schemes, but I thin kthat'd only come up if there was a concept of a "graph" distinct from nodes in the graph traits machinery (ie: if you didn't need fat pointers because you already had access to the graph... anyway))
