--- Comment #17 from Andrew Downing <andrew2085 at gmail dot com> --- Also none of the behavior described in p0593 is required for this C++ program to be well defined. All objects that are required to exists here are created explicitly. It's not relying on the implicit creation of any objects. This is valid C++17 code.
