Maybe we should change that: Instead of using operator+() and operator-() we could have a balance class with functions credit() and debit(). It would have subclasses AssetBalance, LiabilityBalance, and EquityBalance (or maybe follow the European model and just do ActiveBalance and PassiveBalance) whose overrides of credit() and debit() would do The Right Thing.
