- As variadic parameters have the lowest rank in overload resolution, without real usage of `va_arg`, they are commonly used as the catch-all fallbacks in SFINAE. As the front-end still reports errors on calls to `va_arg`, the declaration of functions with variadic arguments should be allowed in general.
