推荐答案

没有。它只是增加了克鲁夫特和开销。

No. It simply adds cruft and overhead.

一个作为维护者搞清楚什么头的不，你将面临的最大的烦恼的需要包含并摆脱他们。 WHE你得到20+标题的列表，你开始考虑丑陋的东西的了野蛮通过它强迫（在删除一个一时间，如果有任何中断看到）。

One of the biggest pains that you'll face as a maintainer is figuring out what headers don't need to be included and get rid of them. Whe you get to a list of 20+ headers, you start contemplating ugly things like brute forcing through it (removing one at a time and seeing if anything breaks).

善待谁必须保持你的东西在未来的人。使用你每个模块所需要的头文件，没有更多的..没有少：）

Be kind to people who have to maintain your stuff in the future. Use the headers you need per module, no more .. no less :)
