I'll start with a general description of the decisions any language designer must consider within a typing model, focusing on the controversial decision of static versus dynamic typing.
我首先简要介绍任何语言设计者在类型模型中必须考虑的一些决策，着重介绍静态类型和动态类型的一些不同的决策。
Initially, it may feel odd to add even more typing information to a dynamic language, after all.
毕竟，开始的时候可能觉得在一个动态语言中加入更多类型信息是多余的。
If you are accustomed to a strongly typed language, dynamic typing seems like a step toward anarchy.
如果您已经习惯了强类型语言，那么动态类型看起来可能会导致混乱。
