No, I never thought of it. I have no idea what purpose calling the next most specific function would serve. Besides, there are ways to call specific functions other than the best match - like casting the arguments to types that make it an exact match with the desired function.

Despite the power of D's overload mechanism, my advice is to use overloading modestly, not cleverly. You've written your best code when a newbie looks at it and remarks "pshaw, I could have written this! Why does Walter make so much money?"
