Sounds like a plan.
One thing though: the RE "[+|-]?\d+(.\d+)?" should be extended
to allow for currency symbols and names in front or after the
Currency for money is a bit like timezones for datetime,
so it's a good idea, not to add it to the base type
interface. However, the interface should be extendable
to include currency information.
