Rob，你创建了Google Go这门语言。什么是Google Go？能简明扼要的介绍一下Google Go吗？](https://github.com/0voice/Introduction-to-Golang/blob/main/Rob%20Pike%E8%B0%88Google%20Go.md#1-rob%E4%BD%A0%E5%88%9B%E5%BB%BA%E4%BA%86google-go%E8%BF%99%E9%97%A8%E8%AF%AD%E8%A8%80%E4%BB%80%E4%B9%88%E6%98%AFgoogle-go%E8%83%BD%E7%AE%80%E6%98%8E%E6%89%BC%E8%A6%81%E7%9A%84%E4%BB%8B%E7%BB%8D%E4%B8%80%E4%B8%8Bgoogle-go%E5%90%97) ##### [2. Go的主要特点是什么？有什么重要功能？](https://github.com/0voice/Introduction-to-Golang/blob/main/Rob%20Pike%E8%B0%88Google%20Go.md#2-go%E7%9A%84%E4%B8%BB%E8%A6%81%E7%89%B9%E7%82%B9%E6%98%AF%E4%BB%80%E4%B9%88%E6%9C%89%E4%BB%80%E4%B9%88%E9%87%8D%E8%A6%81%E5%8A%9F%E8%83%BD) ##### [3. 在我们继续话题之前，能否解释一下为什么Go编译器能达到那么快的编译速度呢？有什么法宝？](https://github.com/0voice/Introduction-to-Golang/blob/main/Rob%20Pike%E8%B0%88Google%20Go.md#3-%E5%9C%A8%E6%88%91%E4%BB%AC%E7%BB%A7%E7%BB%AD%E8%AF%9D%E9%A2%98%E4%B9%8B%E5%89%8D%E8%83%BD%E5%90%A6%E8%A7%A3%E9%87%8A%E4%B8%80%E4%B8%8B%E4%B8%BA%E4%BB%80%E4%B9%88go%E7%BC%96%E8%AF%91%E5%99%A8%E8%83%BD%E8%BE%BE%E5%88%B0%E9%82%A3%E4%B9%88%E5%BF%AB%E7%9A%84%E7%BC%96%E8%AF%91%E9%80%9F%E5%BA%A6%E5%91%A2%E6%9C%89%E4%BB%80%E4%B9%88%E6%B3%95%E5%AE%9D) ##### [4. 让我们开始聊聊Go里的类型系统吧。Go里面有结构（struct）、有类型（type）,那么Go里的类型是什么？](https://github.com/0voice/Introduction-to-Golang/blob/main/Rob%20Pike%E8%B0%88Google%20Go.md#4-%E8%AE%A9%E6%88%91%E4%BB%AC%E5%BC%80%E5%A7%8B%E8%81%8A%E8%81%8Ago%E9%87%8C%E7%9A%84%E7%B1%BB%E5%9E%8B%E7%B3%BB%E7%BB%9F%E5%90%A7go%E9%87%8C%E9%9D%A2%E6%9C%89%E7%BB%93%E6%9E%84struct%E6%9C%89%E7%B1%BB%E5%9E%8Btype%E9%82%A3%E4%B9%88go%E9%87%8C%E7%9A%84%E7%B1%BB%E5%9E%8B%E6%98%AF%E4%BB%80%E4%B9%88) ##### [5. 那么这些方法只是在包内部可见喽？](https://github.com/0voice/Introduction-to-Golang/blob/main/Rob%20Pike%E8%B0%88Google%20Go.md#5-%E9%82%A3%E4%B9%88%E8%BF%99%E4%BA%9B%E6%96%B9%E6%B3%95%E5%8F%AA%E6%98%AF%E5%9C%A8%E5%8C%85%E5%86%85%E9%83%A8%E5%8F%AF%E8%A7%81%E5%96%BD) ##### [6. 你的意思是，我可以给int增加方法，但是必须先使用typedef吗？](https://github.com/0voice/Introduction-to-Golang/blob/main/Rob%20Pike%E8%B0%88Google%20Go.md#6-%E4%BD%A0%E7%9A%84%E6%84%8F%E6%80%9D%E6%98%AF%E6%88%91%E5%8F%AF%E4%BB%A5%E7%BB%99int%E5%A2%9E%E5%8A%A0%E6%96%B9%E6%B3%95%E4%BD%86%E6%98%AF%E5%BF%85%E9%A1%BB%E5%85%88%E4%BD%BF%E7%94%A8typedef%E5%90%97) ##### [7. 你们借鉴了Ruby里开放类的思想，这很有意思。Ruby的开放类实际上是可以修改类并增加新的方法，这是有破坏性的，但是你们的方法本质上是安全的，因为创建了新的东西。](https://github.com/0voice/Introduction-to-Golang/blob/main/Rob%20Pike%E8%B0%88Google%20Go.md#7-%E4%BD%A0%E4%BB%AC%E5%80%9F%E9%89%B4%E4%BA%86ruby%E9%87%8C%E5%BC%80%E6%94%BE%E7%B1%BB%E7%9A%84%E6%80%9D%E6%83%B3%E8%BF%99%E5%BE%88%E6%9C%89%E6%84%8F%E6%80%9Druby%E7%9A%84%E5%BC%80%E6%94%BE%E7%B1%BB%E5%AE%9E%E9%99%85%E4%B8%8A%E6%98%AF%E5%8F%AF%E4%BB%A5%E4%BF%AE%E6%94%B9%E7%B1%BB%E5%B9%B6%E5%A2%9E%E5%8A%A0%E6%96%B0%E7%9A%84%E6%96%B9%E6%B3%95%E8%BF%99%E6%98%AF%E6%9C%89%E7%A0%B4%E5%9D%8F%E6%80%A7%E7%9A%84%E4%BD%86%E6%98%AF%E4%BD%A0%E4%BB%AC%E7%9A%84%E6%96%B9%E6%B3%95%E6%9C%AC%E8%B4%A8%E4%B8%8A%E6%98%AF%E5%AE%89%E5%85%A8%E7%9A%84%E5%9B%A0%E4%B8%BA%E5%88%9B%E5%BB%BA%E4%BA%86%E6%96%B0%E7%9A%84%E4%B8%9C%E8%A5%BF) ##### [8. 你还提到了typedef，是叫typedef吧？](https://github.com/0voice/Introduction-to-Golang/blob/main/Rob%20Pike%E8%B0%88Google%20Go.md#8-%E4%BD%A0%E8%BF%98%E6%8F%90%E5%88%B0%E4%BA%86typedef%E6%98%AF%E5%8F%ABtypedef%E5%90%A7) ##### [9.
