    std::vector<fkyaml::node> nodes = {
        {1, 2, 3}, {{"foo", true}, {"bar", false}, {"baz", true}}, fkyaml::node(), true, 256, 3.14, "foo"};

    for (const auto& n : nodes) {
        try {
            // call size()
            std::cout << n.size() << std::endl;
        }
        catch (const fkyaml::exception& e) {
            std::cout << "The node does not have a container nor string value." << std::endl;
