No, just following ScaledDecimal's example. (0 / 1 is the simplest
zero fraction.)

But I'm not strongly in favour of what I wrote: if 0 (the integer) is
a more sensible zero for Fraction, I'd be perfectly happy with
removing it and so falling back to Number >> #zero. I'm much more
interested in the protocol.
