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.
