Explicitly specifying a ``++void++`` parameter list is required in C, but optional in {cpp}. Using ``++void++`` for a parameter-less function decreases its readability. The at-a-glance impression is that the function _does_ take a parameter, and it takes a second look to ascertain that it does not. Therefore the more compact notation is preferred.
