I wrote the OCamlByExample and I can only say, good luck, I don't think OCaml is ready for production, and it's generally not a very user-friendly language, but IMO it's all about having fun first and if this is what makes it fun for you guys then you should do it!
Also with LLMs it's probably easier to just feed the compiler errors to an LLM and get something readable at the end.
All fine and good if you don't like it for whatever reasons, but AFAIK, people have been using OCaml software as parts of tech stacks in critical industries for around 20 years. So unless you have some qualifications to offer,
> I don't think OCaml is ready for production
seems to indicate your thinking is just not based on fact. This position is further belied by the stack of successful production applications you can see at https://ocaml.org/industrial-users/businesses.
