This turns out to be quite important, as several important standard library types (such as `std::string`) have mixed-access overload sets for their constructors as an implementation detail. The overall approach here is: - Use the most permissive access to determine the access of the overload set itself. This affects whether name lookup finds the member name at all. - After overload resolution, re-check the access of the selected member, if it's protected or private. --------- Co-authored-by: Dana Jansens <danakj@orodu.net>
