#include <experimental/filesystem>
#include <iostream>
namespace fs = std::experimental::filesystem;
int main()
    std::cout << fs::path("/foo/bar.txt").stem() << '\n'
              << fs::path("/foo/.bar").stem() << '\n';
    for (fs::path p = ""; !p.extension().empty(); p = p.stem())
        std::cout << p.extension() << '\n';
