,这一点在豆包下载中也有详细论述
However, only in theory, i.e. in McCarthy's papers! :). in practical terms, I don't think there is any practical Lisp, more than toy examples, based on only those first 5, or 9 or 7 or how many forms McCarthy thought at some point in time are "basics". Emacs does not have statements on which are "elementary forms". C core implements ~1700 of "primitive" forms. Graham came up with 17 for Arc. Common Lisp has 25. Now, I have never used Arc, but I am sure that none of Common Lisp implementations in Common Lisp are implemented directly on top of only those 25 so called "special operators", even though, in theory that might have been the idea. Of course I don't know for sure, I discovered Lisp after the Lisp, and am just learning this myself, but to be practical you have to talk to the outside world, and outside world is often a bit more complex than what those 25 forms cover.However, only in theory, i.e. in McCarthy's papers! :). in practical terms, I don't think there is any practical Lisp, more than toy examples, based on only those first 5, or 9 or 7 or how many forms McCarthy thought at some point in time are "basics".

在叙事语言设计层面:语法必须让创作者感到自然流畅,避免阻碍创作过程,并通过清晰直观的方式提供表达叙事意图的机制(包括分支结构、动态变化、角色设定、状态管理)。
