So, all the code in the world that is meant to be ported up the an ANSI standard for C++ has already been so ported, we could remove all notion that the scoping changed from the warnings given new C++ (any ISO C++ and later). The old semantics and warning can remain for users that select the old languages. This means that in 5 years, once the new compiler is released distributed, and everyone has it in their OS distribution, we could _then_ not get the warning anymore and we could then write code that way. We could also maybe turn the warning off, with -ffor-scope, if that works. The benefit of that is we could then do that now and start using that style of code now. We should excise that warning in any event.
