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.
