Universal references with functions

Question

What is the type of "univ" in the code below?

template<typename T>
void func(T&& univ) {
    // ??
}

int sum(int a, int b) {
 return a+b;   
}

int main() {

    func(sum);

}

I didn't know that universal references also worked with functions. Is func(sum); equivalent to func(&sum); or is the rvalue reference binding itself to something else than a simple pointer?

I feel like we just had that question... [edit] Here it is: http://stackoverflow.com/q/31125447 — Kerrek SB, Jul 01 '15 at 22:58
You can check types with following trick `template void type_is();` [DEMO](http://coliru.stacked-crooked.com/a/77c1704901003313) — Evgeny Panasyuk, Jul 01 '15 at 23:02

I don't really know how to put this into more words...

The type is reference to function taking two ints and returning and int

or, as a comment says: int(&)(int, int)
