defer应该是go中比较特殊的一个关键字了，其他的编程语言还真没见过这个关键字的。这个关键字使用起来非常方便，以栈序的方式，将所要做的操作延后处理，特别适用于资源回收等应用场景，不可谓不赞。但是呢，这个defer还是有个小小的坑的，下面我们就来看看一个例子：

刚同事问我关于SQL中的JOIN的知识，我回答地不严谨，故而，在此一本正经地整理记录一遍吧，结合一个实例，以期把简单的事说透彻吧。
首先我们来说一个例子，一会我们会用到的，假设我们在给小朋友们分零食，按照他们的岁数准备的，不能弄错：

Go语言号称是“面向接口编程”的语言，interface就是那个神奇的接口，因此，相信学习的Go的人都会重视这个概念。
本文不打算一一详细说interface的所有的用法和概念，只打算挑一些自己认为的重点难点和容易出现坑的地方来说一说。
