printing an initializer_list

template<typename T>
void print(std::initializer_list<T> const& x)
{
    for (auto it = x.begin(); it != x.end(); ++it)
    {
        // ...
    }
}

template<typename T>
std::ostream& operator<<(std::ostream& os, std::initializer_list<T> const& x)
{
    for (auto it = x.begin(); it != x.end(); ++it)
    {
        // ...
    }
    return os;
}

int main()
{
    print( {4, 8, 15, 16, 23, 42} );     // works
    
    std::cout << {4, 8, 15, 16, 23, 42}; // does not work
    std::cout << std::initializer_list<int>( {4, 8, 15, 16, 23, 42} ); // too clumsy
}
