保持简单
简单是复杂的最高境界。

你一定听过这个建议：
KISS
（
Keep it simple, stupid
）。意思就是：“保持简单，笨蛋。”一
个人要有多么愚蠢才会把这当成耳旁风呢？简单无疑是极好的目标，当然应该在代码中努
力实现它。没有哪个程序员愿意处理过于复杂的代码。简单的代码透明、结构清晰、

为什么不是所有的代码都这样？
在程序员的世界中，有两种简单：
错误的
和
正确的

以最简
单的方式写代码、抄近路、忽略所有烦人的复杂之物（把它们都隐藏起来，希望它们消
失），做一个简简单单的程序员就好。
要是我们要的简单有这么“简单”就好了。但是在现实世界中，很多程序员确实用这种
方式编写简单代码。他们根本不动脑子，有些人甚至对自己做错了什么完全没有意识，
对自己正在编写的代码没有充分考虑。对于代码中所有固有的微妙复杂性，他们几乎不
了解。
不动脑筋的方法不能产生简单的代码，而会产生
过于简化

重重。由于考虑不周，代码和需求便不能匹配：通常只考虑表面可见的部分，忽略错误
处理，不能处理任何非常规的输入。因此，过于简化的代码是
