Your argument doesn&#x27;t add anything really. You can make anything in any reasonable language.<p>When people say &quot;you can add X to Common Lisp&quot; or &quot;you can make X in Common Lisp&quot;, they usually mean that you can integrate such a feature in Lisp.<p>If you mean &quot;you can write a compiler in Lisp&quot;, then, obviously. But you can do that in C++ too.<p>Not a single reply has demonstrated that you can effectively and reasonably add those features (to their fullest extent) to Lisp. They all replied saying that you can do things like write a new language (e.g., Shen), perhaps by using Common Lisp as your implementation language.
