Vacuous truth is a hard concept even for experts and mathemeticans.If you really believe that, you'd also promote the abolishion of the empty set (a vacuous collection of objects)
Actually, I _would_ advocate abolishment of the empty set from IEEE 1788!I my opinion and personal experience, empty set is totally unnecessary. We don't have empty set in our Kaucher interval arithmetic library now for five years. It makes the code fast and simpler due to less special cases.
