说明：   ”Lisp-1”系统使得贯彻函数式编程的风格更加容易，而”Lisp-2”系统则使得宏编程更不容易出错。确切的细节有一点麻烦，如果你真的想 了解技术上的影响，你可以阅读此文。
(" Lisp-1" system makes the implementation of functional programming style is more easy, " Lisp-2" system was to make macro programming less error-prone. The exact details are a bit of trouble, if you really want to understand the impact of technology, you can read this article.)
