`cloc` has it at 24k lines of code so it's by no means a huge project but it's big enough where I feel like we would have encountered a large variety of issues. As of yet there hasn't been anything major. We have felt the lack of libraries at times but that just means we need to write more lisp, which is a good thing as lisp is fun.

Honestly, I don't know that I'd classify our use of CL as dynamic. We're happy customers of `deftype` and `declaim`. While it's true that not every function makes use of them, most of them do. So in that regard, I can't comment but that's the beauty of lisp: it's the language that you need it to be.
