王垠抨击过缩进语法。其中提到缩进很容易在编辑的时候弄坏，比如不小心（猫跳到键盘上？）输入或删去一些空格。而传统语法没有这个问题是因为恰好输入或删除成对的符号（花括号对或begin/end对）的概率小多了。比较来说，缩进是单点变更就会产生语义差异，因而危险。

需要承认这是一个合理的责难。其实可以和 rm -rf / temp 的空格惨案相类比。紧凑的语法往往造成这种问题。

不过实践上似乎并未看到或听到很多实际的惨案，即使coffee、yaml已经相当普及。

有一些方法来克服这一问题：

  • 受控的编辑环境
  • 语法冗余结构
    • 引入类似花括号或begin/end的要素
    • 引入类似/的terminator
