Member function template with the number of parameters depending on an integral template parameter

Question

I have the following class template:

template
class MyClass;

where T is some type, N - num

Answer 1

Why not use a static_assert?

template 
class MyClass
{
public:
    template 
    void foo(Args&&... args)
    {
        static_assert(sizeof...(Args) == N, "Wrong number of arguments.");
        // Rest of the implementation.
    }
};
