Template Specialization for T -> std::vector

Question

I have a template class method

template
T pop();

Now I want to do a template specialization as follows,

Answer 1

A possible solution is a non-member function implemented like this

template 
struct classname_pop
{
    static T pop(classname &obj) { return obj.pop() ;}
}

template 
struct classname_pop>
{
   static std::vector pop(classname &obj) {obj.specialized_pop() ;}
}

template 
T classname_pop(classname &obj)
{
   return classname_pop_t::pop() ;
}
