Variadic Templates

[Zephilinox]

I'm looking for a way to enter an unlimited amount of types in the <> part of a template function, I found Variadic templates but I'm not sure if it can do it, all the examples I've found are similar to the C argument list and don't use the <> part of the template at all.

I tried this, but the overload is ambiguous, can anyone offer a solution?

#include <iostream>
#include <typeinfo>

template<typename T>
void stuff()
{
    std::cout << typeid(T).name() << "\n";
}

template<typename T, typename... Args>
void stuff()
{
    std::cout << typeid(T).name() << "\n";
    stuff<Args...>();
}

int main()
{
    stuff<int, float, double>();
    return 0;
}

You can get rid of the ambiguity by letting the second stuff() take one extra template argument.

#include <iostream>
#include <typeinfo>

template<typename T>
void stuff()
{
    std::cout << typeid(T).name() << "\n";
}

template<typename T1, typename T2, typename... Args>
void stuff()
{
    std::cout << typeid(T1).name() << "\n";
    stuff<T2, Args...>();
}

int main()
{
    stuff<int, float, double>();
    return 0;
}
