I'm surprised that anyone finds multiple inheritance so singularly important. Single inheritance is really only crippling if two kinds of objects have to inherit from a common base in order to be substitutable. Remove that restriction and inheritance is properly reduced to the mere code/data reuse hack that it is. If anything, lack of multiple dispatch probably hurts more than lack of MI. > Wherever you stand on OO as a programming paradigm, you can't deny > that single inheritance is the weakest variant of it. I can place my standpoint almost anywhere in the OO programming paradigm, yet not see this. Sorry, George!
