A bit off-topic but the post title will probably attract relevant people.

What are the thoughts on OCaml on HN?

It replaced Python for everything longer than a couple hundred of lines long for me. Fast language, fast compile times, clean(-ish) syntax, strong typing system, good ecosystem, and now multicore support? Yes please!

I must be more nuanced, though: existing libraries in opam are generally very, very good (I really like cmdliner), but many things may be missing. There is no alternative to Django, for instance. No serious IDE, except emacs. The standard library was so lacking that there is at least an alternative. The situation improved, but there's still missing stuff compared to Python.

and vim, and visual studio, and whatever else supports the LSP protocol via https://github.com/ocaml/ocaml-lsp

While janestreet does have an publish their own stdlib, I personally try to stick to the stdlib whenever possible. Not to knock janestreet. I'm glad they're around and have contributed a bunch.

But overall I agree with you. It's been my favorite language to write in for years now. You can't just reach for off-the-shelf libraries for every little thing. Although the ones that do exist tend to be written halfway decently.
