I'd say it makes more sense for someone else to implement these features
as helper functions or classes.  They're not directly part of the
Decimal system.  Facundo got roped into this because he wanted a Money
class and was persuaded to do the finishing work for getting Decimal
into Python as the basis.  Seems to me this is in the same category of
building some additional capabilities on top of Decimal.
