I agree wholeheartedly with this post; the justification stated above is, quite frankly, nuts. What it means is that the developer is compelled to make a data member public that he'd rather not, which is bad. If the intent of the standard was to prevent the client from discovering a way of misusing a class, I have some very bad news: in C++ it is always possible for the client to misue a class. That's a non-issue, utterly beside the point. Regards, Daniel Parker -- Please do not use reply, use danielp@anabasis.com instead. --- [ comp.std.c++ is moderated.
