Laravel has a powerful Inversion of Control (IoC) / Dependency Injection (DI) Container. Unfortunately the official documentation doesn't cover all of the available functionality, so I decided to experiment with it and document it for myself. The following is based on Laravel 5.4.26 - other versions may vary.

I won't attempt to explain the principles behind DI / IoC here - if you're not familiar with them you might want to read What is Dependency Injection? by Fabien Potencier (creator of the Symfony framework).

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

• Array 是 value type，使用 structs 实现
• 数据类型没有隐式转换
• 对于 String，count() 的复杂度是 O(n)，每一个 Character 都是 unicode scalars 的序列
• raw values 和 associated values 的区别
• 如果必要，对于实现了 _ObjectiveCBridgeable 的 value types 会被自动桥接成 reference types
• 讲一下 unowned 和 weak 的区别
• 改 struct 的属性的方法名前要加 mutating，但如果这个 struct 用 let 声明的，改不了。修正：网友指出用 nonmutating set 也可以改属性。
• nil 和 .None 的区别
• capture list in closure
• 举一个 guard ... where 的例子
