Magnitude (as opposed to identity -- "is") comparision of a FixedPoint to a
non-numeric object makes no sense that I'm comfortable imposing, so I'm
happy to let it raise an exception.  Specific apps may require more, and
through the magic of subclassing you can supply whatever senseless <wink>
comparison behavior you like without touching the base code.

In any case, this isn't a maintained module.  Whatever time I may have been
able to devote to it I set aside in case Aahz hits snags implementing IBM's
Standard Decimal Arithmetic proposal:

FixedPoint gets the job done for most who've tried it, but it's at odds with
IBM's proposed model, and I like IBM's well enough that I'd rather help it
become a standard.
