It appears that in C++20, we’re getting some additional utility functions for smart pointers, including: template<class T> unique_ptr<T> make_unique_default_init(); template<class T> unique_ptr<T> make_unique_default_init(size_t n); and the same for std::make_shared with std::shared_ptr. Why aren’t the existing functions: template<class T, class… Args> unique_ptr<T> make_unique(Args&&… args); // with empty Args template<class T> unique_ptr<T> make_unique(size_t n); enough? Don’t the…
