定义过度出租的优点 [英] Advantages of define over let

问题描述

在与 Racket 的主要作者之一 Matt Flatt 的对话中，我被告知(顺便)社区不推荐使用 let 形式，主要被 define 取代.

define 与 let 相比有哪些优势，会促使 Racket 社区选择使用它来代替 let?>

作为参考，define 和 let 链接在此处.

解决方案

减少向右漂移"

参见第 4.2 节的定义:https://docs.racket-lang.org/style/Choosing_the_Right_Construct.html

也就是说，我认为这主要是一种品味问题.

During a conversation with Matt Flatt, one of the primary authors of Racket, I was told (in passing) that the let form is not recommended by the community and is largely being replaced by define.

What are the advantages of define over let that would prompt the Racket community to elect to use it in place of let?

For reference, define and let from the Racket documentation are linked here.

解决方案

"To reduce rightward drift"

See the section 4.2 on definitions: https://docs.racket-lang.org/style/Choosing_the_Right_Construct.html

That said, I see it mostly as a matter of taste.
