同音性究竟是什么意思? [英] What exactly does homoiconicity mean?

问题描述

我试图理解维基百科关于同质性的文章，但它太冗长，并没有解释背后的主要理论这个词简明扼要.我应该补充一点，我的母语不是英语，所以我更喜欢简单的英语而不是学术白皮书引用.

I was trying to understand the Wikipedia article on homoiconity, but it's too verbose and does not explain the main theory behind the word concisely. I should add that I'm not a native English speaker so I prefer simple English over academic white paper quotes.

那么，如果一种语言是同音异义的，这究竟意味着什么?是什么让 C#、Java 或 JavaScript 变得非同形异象?

So, what exactly does it mean if a language is homoiconic? What makes C#, Java or JavaScript non-homoiconic?

推荐答案

意为代码即数据"，这是 Lisp 家族的一个普遍特征.

It means "code as data" which is a general characteristic of Lisp family.

(add 2 3)

就像上面的字符串一样，它既是一个列表，也是一个函数调用.Homo"前缀代表这个特征.

Just like above string, which is both a list and also a function call. The "Homo" prefix stands for this characteristic.
