这些程序员也会倾向于依赖他们的第一想法，尤其是当他们已经写了代码的时候。

These programmers then have a tendency to get attached to their first ideas, especially when they've already written the code.

同时，他们可以更快的写代码，因为他们有一个清晰的图片告诉他们什么是需要的。

They also write code faster, because they have a clearer picture when they start of what's going to be needed.

接下来的部分将描述他们是如何运行的，并通过实例代码演示了一些特殊的设计点。

Their operation is described in the next sections followed by example code to illustrate particular design points.

That goes back to that idea of sort of discipline coding. It's easy to have assumptions about what you think are going to come into the program when you writ it. If you really know what they are use them as search, but if you think there's going to be some flexibility, you want to prevent the user getting trapped in a bad spot, and exceptions as a consequence are a good thing to use.

这又回到了规范编码的想法上来了,在你写代码的时候考虑,什么会进入你的代码的思考是简单的,如果你真的知道,他们是用他们来做搜索的,而你希望有一定的灵活性，你想要阻止用户,陷入一个艰难的境地,那么异常是非常实用的。
