But no seriously F# might actually be the perfect agentic coding language. I had the good fortune of learning OCaml a few years ago as the models were getting good. Had a blast.
I think Lisp and an ML are kind of the dynamic (static) duo. I still think MLs are the best for complex projects, but interpreted languages are pretty neat too. Python, Rust, and Golang are all great, also.
I think a tree calculus language might be the actual best - but it's too soon to say
Really, languages are great for LLMs.
