So? Tagged types has a currency type. As long as you provide a way to
extract which currency is meant, people can join on conversion tables.
Now that I think of it, enum's have the necessary machinary already to
map OIDs to strings so you're nearly all the way there... (Except
ofcourse taggedtypes didn't prevent you from adding more currencies
later, which enums don't currently allow you to do).
Have a nice day,
