I just meant that map would be interesting on top of that (for vectors which might not be array based). I agree, it needs further thought. Contrary to what I was satying previously, the visitor pattern might still be a worthy option, since it allows nive idioms like v.walkInXxxOrder(EbeMultiply.by(w)), where EbeMultiply would be the class of the visitor, and EbeMultiply.by a factory method which keeps a reference to w. I've implemented that locally, it reads quite well. The downside is that the visitor keeps a local copy of w. Sébastien
