OCaml 4.14 compatibility #44
Description
Although the tool already supports OCaml 5, some OCaml users still have not moved to the latest versions and remain on OCaml 4.14. This version is provided with long term support (https://ocaml.org/releases/4.14.2, https://github.com/ocaml/ocaml/milestone/47). When discussing with other developers offline, some have shown interest in the tool and use OCaml 4. I suggesting supporting OCaml 4.14 in a specific branch. This support would not be actively maintained. It may be maintained opportunistically (fixing easy issues, accepting PRs, ...).
