struct constructor_specialized
{
    constructor_specialized() requires(std::is_same_v)
    {
        std::cout << "Specialized Constructor\n";
    };

    constructor_specialized()
    {
        std::cout << "Generic Constructor\n";
    };
};

int main()
{
    constructor_specialized int_constructor;
    constructor_specialized float_constructor;
};

Run the code here.
