But that is not obvious at all. It's merely a historical accident that things currently work like this. And the reason we should require that there *always* is a defined order is that programming languages are the means by which we instruct computers what to do, and permitting ambiguity in the language is useless and can only lead to error. --- [ comp.std.c++ is moderated.
