to evaluate by looking at code: functions may return in places you don’t expect. This causes maintainability and debugging difficulties. You can minimize this cost via some rules on how and where exceptions only intended for use in the implementation, without considering its impact on the API, or on maintainability. • Aliases can create risk of name collisions • Aliases can reduce readability by giving a
