However, none of this seems to deal with the major problems with the
money type right now:

- Only supports one currency (dollars)
- Only supports one scale (yen has no decimal normally, but what if you
want to track hundredths of a dollar-cent?)

My question, what is this Money64 type buying you over just storing an
integer in your database? There should be some value-add somewhere, but
what is it?

I've written applications tracking money using just an integer, if
there were a special money type, I'd expect it to do something more.

Have a ncie day,
