Don't get me wrong, they do work with lisps already, had plenty of success having various LLMs creating and managing Clojure code, so we aren't that far off.

But I'm having way more "unbalanced parenthesis" errors than with Algol-like languages. Not sure if it's because of lack of training data, post-training or just needing special tokens in the tokenizer, but there is a notable difference today.
