64-Bit Bank Balances ‘Ought to Be Enough for Anybody’?
This only puts currency codes in the type system; and uses rational numbers for amounts.
This is definitely useful because you can have the type system tell you if you've implemented e.g. exchange rate conversion incorrectly. But it's also a hassle because you need to reify currency values discovered at runtime as types, which isn't pretty [1].
