But this is easily done by creating a custom class -- which has the
advantage that the set of constraints can be specialized to the needs
of a specific application.  When we add a monetary type to the
language we'll never get it right for all apps.  OTOH, I think we
could get a fixed point type right.

How many other languages have a monetary type?

What support for money does SQL have?
