Defensive programming constructs have prevented many a defect, but the constructs themselves tend to litter code with repetitive logic.

防御性编程结构阻止了一个又一个缺陷，但这些结构本身却不免为代码添加了重复的逻辑。

The "error" type unambiguously reflects a defect in the program logic: Purify is reporting a program bug and that's what you need to hear.

“错误”类型很明显反映了这个程序逻辑中的缺陷： Purify 报告了一个程序的错误，那也正是您所想要的。

The logic to fix the defect is quite similar to the logic in pop(), as you can see in Listing 27.

修复这个缺陷的逻辑类似于 pop() 的逻辑，如清单 27 所示。
