I don't understand why this had to be LLM generated. S-expression syntax parsers are not hard to write. That's rather much the point of S-expressions.

I'm not sure I quite understand the point of your comment.

Are you implying that LLMs should be used for very hard to write code? I feel like the best use of LLMs is to automate the easy stuff so that I can focus on the hard to write stuff.
