I would almost agree that blindly eliminating shadowing will lead to bugs, but they will be shallow bugs detected almost immediately. The bugs I am particularly interested in avoiding are the difficult bugs that seem to be intermittent, that only hit in certain rare situations and that take ages to find. I will gladly trade you a hundred of the first for one of the second :-).
