Call it what you will, but I have put on a rigorous mathematical basis the longstanding practice (nearly two centuries) of leaving 0^0 undefined. And we still have x^0 = 1 and 0^x = 0 for all natural numbers x=/=0.
If you find this "inconvenient," that really is too bad. Learn to deal with it, Barty.
