The funny thing about Lisp is that writing a Lisp interpreter is significantly fewer keystrokes than correctly installing Common Lisp and its tooling. The ratio of lisps to lisp programmers may actually be above 1.
> The best LISP is the one you create yourself. You learn so much about programming by implementing your own language, and LISP is brilliant for this purpose thanks to its simple syntax and homoiconicity (code is data, data is code). It's also a great way to learn a new existing language, like Rust or Go, by writing a LISP interpreter with it.
