variadic functions template type traits

template<typename ...Args>
bool MyClass::dynaWraper(std::tuple<Args...> & res)
{
    std::list<std::string> from_sth{"a", "1"};
    // do some convert, to fetch in `res` with diffrent type.
}

And test code maybe like this,

std::tuple<std::string, int> tp;
MyClass c;
c.dynaWraper(tp);

So, how to do to let it work?I broke down.
