The `Money` type pairs a currency code with an exact `Decimal` amount. Arithmetic on `Money` values enforces matching currencies at runtime.

```vary-snippet
from money import of
from decimal import parse

let price = of("USD", parse("29.99").unwrap())
let tax = of("USD", parse("2.40").unwrap())
let total = price + tax    # Money(USD, 32.39)
print(total)
```
