Variadic template events telling me "too few arguments"

I'm using the new version of the compiler and decided to try out the variadic templates functionality to make an event class: template<typename... $arguments> class Event { public: std::vector<void (*)($arguments...)> Handlers; public: Event(); ~Event(); void Attach(void (*callback)($arguments...)); void Detach(void (*callback)($arguments...)); void DetachAll(); void operator()(); flow IsHandled() const; }; This is what it looks like, but when I use it in main.cpp: void TestFunc(int arg, float arg2) { system("pause"); } Event<int, float> evt; evt.Attach(TestFunc); evt(); It tells me "Error 1 error C2198: 'void (__cdecl *)(int,float)' : too few arguments for call" This is what should happen when it's called: template<typename... $arguments> void Event<$arguments...>::operator()() { for(inti = 0; i < Handlers.size(); i++) { (Handlers)[i](); } } I also tried with (Handlers)($arguments...) and also (Handlers)(...$arguments) and (Handlers)($arguments), and it changes nothing, it still tells me too few arguments.Does anyone have experience with variadics?
