为什么大多数S-Expression语言是动态键入的? [英] Why are most S-Expression languages dynamically typed?

问题描述

大多数Lisps和Schemes是如何动态键入的? 静态类型是否不能与它们的某些常用功能混在一起?

How come most Lisps and Schemes are dynamically typed? Does static typing not mix with some of their common features?

推荐答案

可以使键入和s表达式协同工作，请参见

Typing and s-expressions can be made to work together, see typed scheme.

在某种程度上，动态地表达S表达式语言是历史的巧合.这些语言倾向于更加依赖 macros ，并且对s表达式进行解析和模式匹配的简便性使得宏处理变得更加容易.大多数有关复杂宏的研究都是在s表达式语言中进行的.

Partly it is a historical coincidence that s-expression languages are dynamically typed. These languages tend to rely more heavily on macros, and the ease of parsing and pattern-matching on s-expressions makes macro processing much easier. Most research on sophisticated macros happens in s-expression languages.

类型化的卫生宏很难.
