I have a template class that has a template copy constructor. The problem is when I instantiate this class using another instance of this class with the same template type, my template copy constructor is not called. Why doesn't it match?

Here is the code snippet:

#include 

template 
class MyTemplateClass
{
    public:
        MyTemplateClass()
        {
            std::cout << "default constructor" << std::endl;
        }

        /*
        MyTemplateClass(const MyTemplateClass& other)
        {
            std::cout << "copy constructor" << std::endl;
        }
        */

        template 
        MyTemplateClass(const MyTemplateClass& other)
        {
            std::cout << "template copy constructor" << std::endl;
        }
};

int main()
{
    MyTemplateClass instance;
    MyTemplateClass instance2(instance);
    return EXIT_SUCCESS;
}

default constructor

default constructor
copy constructor
