basic_decimal can utilize fundamental operations from the traits
class to provide the full interface.  Put another way, the traits
class needn't provide the entire interface that basic_decimal
provides, so adapting a new type to fulfill the basic_decimal
interface is easier.  (That's theoretical, of course.  I haven't
any idea how much logic Daniel's basic_decimal implements beyond
that provided by his traits class.)
