[edit] Example

#include #include #include   int main() { std::string str { "C++20" }; auto view = std::views::common(str);   std::string copy_of_str = view.base(); std::cout << "copy of str: [" << copy_of_str << "]\n"; std::cout << "view.base(): [" << view.base() << "]\n";   std::string move_str = std::move(view.base()); std::cout << "moved str: [" << move_str << "]\n"; std::cout << "view.base(): [" << view.base() << "]\n"; // unspecified }

Possible output:

copy of str: [C++20] view.base(): [C++20] moved str: [C++20] view.base(): []
