Yes, the delegate needs the parentheses but the function does not:

int DG() {return 42};
int delegate() getDG() {return &DG};

auto dg = getDG; //OK
auto ??? = getDG();

The last line could be a call to getDG with optional parenthesis,
so ??? = DG. Or it could be a call to getDG without optional
parenthesis and a call to the returned DG, so ??? = 42.
