I have found that being able to report these exceptions with a specific error code (instead of a generic exception or, even worse, no reported error) has saved me hours tracking bugs.

我发现，在跟踪错误时，用特定的错误码(而不是一般的异常或—甚至更糟—不报告错误)来报告这些异常节省了我数小时的时间。

The state tracking code is highly repetitive, error prone and, generally speaking, a chore to write and maintain.

状态跟踪代码的重复性很高，而且很容易出错，一般而言，编写和维护该部分是很繁琐的。
