```Ruby
irb(main):006:0> "($100)".money
Currency::Exception::InvalidMoneyString: "($100)" USD "(100)": {:state=>"(100)", :currency=>#, :string=>"($100)"}
```

This is standard issue in the finance industry. There should also be an output option (like Rails' money formatter) to output in this format.
