While one can find levels of indirection to translate between one and the other, that doesn't mean they're equivalent. It's like saying that because I can make an equivalence between the complex plane and the real, that they should be treated as equivalent. But they shouldn't -- else you run into a domain error. -- MarkJ Tacoma, Washington
