With regards to multiple return values in "By-Reference Parameter Papercuts", you can make it more ergonomic with initializer list and structured bindings without having to use std::make_tuple and std::tie:

    auto get_multiple_values(const bool condition)
    -> std::tuple<bool, int>
    {
        if (condition) {
            return {true, 5};
        }

        return {false, 0};
    }

    void foo()
    {
        auto [status, value] = get_multiple_values(true);
    }
