Hello late: Common Lisp does quite a lot of compile-time type checks though: https://lispcookbook.github.io/cl-cookbook/type.html https://lispcookbook.github.io/cl-cookbook/type.html it's not as extensive as type-safe languages, but clearly far better than any interpreted one. Add the interactivity where you compile a function (yes, just a function) with a keystroke and thus get the errors or warnings instantly, that makes a pleasant experience.
