Great! > I think of it more as recognizing that full multiple inheritance > never achieved "traction" in the programming language marketplace, Well, that's debatable, but I think the rationale for leaving direct support for MI of implementation in Ada 95 is still valid, and in a language like Ada which has other means of abstraction I don't miss it much. > but that multiple inheritance of interfaces has shown itself to > have a good cost/benefit ratio.

Seems like something on my end, but neither home nor work allow me to connect.
