C++ Lambdas and Variadic Templated Wrappers

I am trying to execute the following code in C++. The program converts a lambda with no capture to a function pointer.

#include <utility>

template <typename R, typename... Args>
R run(R (*func)(Args...), Args&&... args) {
        func(std::forward<Args>(args)...);
}

int main() {
        run([] (int x, int y) {
            return x + y;
        }, 100, 200);
        return 0;
}

However, when I compile it, I get the following error -

test.cc: In function ‘int main()’:
test.cc:11:20: error: no matching function for call to ‘run(main()::<lambda(int, int)>, int, int)’
         }, 100, 200);
                    ^
test.cc:11:20: note: candidate is:
test.cc:4:3: note: template<class R, class ... Args> R run(R (*)(Args ...), Args&& ...)
 R run(R (*func)(Args...), Args&&... args) {
   ^
test.cc:4:3: note:   template argument deduction/substitution failed:
test.cc:11:20: note:   mismatched types ‘R (*)(Args ...)’ and ‘main()::<lambda(int, int)>’
         }, 100, 200);
                    ^

As far as I am aware this is fine. I have also tried explicitly giving the template arguments in the call to run. That doesnt work either.

Any ideas?
