You can make either mechanism do what you want by defining the right set
of functions. If a minimum of one argument per variadic parameter is
required, you can work around it by defining an extra function with no
variadic parameter to handle the zero-argument case.
So, although I agree with you, I don't have a strong opinion, and I'm
happy with either.
