Quite appropriately for an Ada newsgroup, you are setting up a straw man argument. The most typical use for multiple inheritance involves inheriting from unrelated classes. And in C++, combining multiple inheritance and templates is extraordinarily powerful. In any case, examples of cases where multiple inhertiance is not appropriate are not arguments against multiple inheritance. If I gave you an example where tasking was inappropriate, would that be an argument to remove it from the language?
