I think you and John are meaning different things by "outside the scope of the parent function". He took it to mean "the scope of the parent function has ended due to the function returning". In that case what he said is *indeed* correct. And you cannot call nested functions like that in Pascal either - the parent function has to be at least *active*. > >Maybe you could explain how local functions that could not be >called from outside the enclosing function scope would be a >useful addition to C++.

That is my main objection to nested functions - it adds too little for the pain. --- [ comp.std.c++ is moderated. To submit articles, try just posting with ] [ your news-reader.
