修复Lisp语法 [英] Fixing Lisp Syntax

问题描述

成为Lisp的新手，我想知道Lisp语法是否可以修复"?

Being a newbie to Lisp I'm wondering if the Lisp syntax could be "fixed"?

有人说Lisp的语法是其最大的优点之一.我不太明白这一点.

Some people say the syntax in Lisp is one of its biggest strengths. I don't quite understand this.

用空白，换行和缩进的组合来代替明显的"括号是不可能的吗?就像在Python中一样?

Isn't it possible to replace "obvious" parentheses with a combination of white spaces, new lines and indenting? Just like in Python?

在我看来，括号是Lisp代码中最常用的字符.我想知道这是否是正确的-但是如果是这样，这是否暗示语法有一些冗余?

It looks to me like parentheses are the most used characters in Lisp code. I'm wondering if that's true - but if it is, isn't this a suggestion, that there is some redundancy in the syntax?

这个问题是否有一些简单的答案-为什么会有这么多括号?

Is there some simple answer to the question - why so many parentheses?

例如:

(defun factorial (x)
    (if (= x 0)
        1
        (* x 
           (factorial (- x 1)))))

为什么不呢?

defun factorial (x)
  if (= x 0)
    1
    * x
      factorial
        - x 1

例如在行的结尾处关闭括号，并始终在新行中将其打开. 只有1会是模棱两可的-是1还是(1)-但是我们可以引入一个例外-单个标记未列出".

e.g. close parentheses at the end of line, and always open them on new lines. Only the 1 would be ambiguous - is it 1 or (1) - but we could introduce an exception - single tokens are not "listified".

这行得通吗?
