Be able to duck this question was precisely why I put Decimal to the left of Fraction in my pragmatic tower, btw. There are all sorts of good reasons why that order was mathematically wrong (Real vs Rational, representability of NaN/Inf, etc), but from the point of view of providing clearly defined behaviour for an atypical operation, it should be a lot easier.
