Dave Thomas: Yes, once you adopt a discipline of separating the abstraction and the data that abstraction is working on, your code starts being structured in a far tidier way. Your code tends to be decoupled and orthogonal.

戴夫·托马斯：是的，一旦你采用了这种方法，将数据和作用于其上的抽象分离，你的代码就会开始变得更加有条理、结构更好，你的代码的耦合程度会更低，更具正交性。

I'm strongly against the death penalty — it's an eye for an eye.
