But it should still be made clear that step two involves binding the function parameters in order, not just accumulating a set of values (and references) to be passed to the function. Evaluating an expression used as an argument and constructing a function parameter aren't so obviously the same that it can go without saying. Remember, one thing that this process is meant to fix is the f(auto_ptr, auto_ptr) problem. --- [ comp.std.c++ is moderated. To submit articles, try just posting with ] [ your news-reader.
