picked up ocaml back when prepping for some interview round, didn’t expect much just wanted the functional knowledge. but later used it for advent of code and it just worked so clean. pattern matching, recursion, immutabilitty.. fits those problems naturally. ended up liking the language way more than planned.

Loved using OCaml for a compiler course at uni when I was a student. But I've always felt that the tooling side is pretty rough, especially on Windows. Opam recently added Windows support, but it involves installing MinGW, and when following the official docs https://ocaml.org/docs/installing-ocaml#install-platform-too... the process breaks down with an error when trying to install utop due to a path separator error, which one has to fix manually (at least that was the case last time I tried). By comparison, installing Python or Rust on Windows is a breeze.

Even in Linux, I'd say the tooling is a bit rough, dune and the new lsp are going in the right direction though.

Dune is a very powerful and good build system — it can do some very magical and useful things. The only problem is most of these useful features are very poorly documented…

If I learned OCaml, what type of prospects would I have?

Fairly seasoned generalist, mostly writing Go these days. Lots of plumbing with LLMs etc.

Would love to learn something new but am driven by a goal in mind (ie OCaml exposes me to "X industry")

Is that a thing?

Learning OCaml exposes you to the sadomasochist industry, that's about it.

Not sure about OCaml but I learned Haskell recently which made me think about programming diferently and appreciate it more.

I think learning a functional language is 100% worth it because it introduces you to many different concepts, any statically typed functional language should be good for this.

Generally I think learning new paradigms of languages is worth it. Nice to have an alternative perspective on solving the same problems.

EDIT: Not sure about OCaml serving as an introduction to a particular industry. Compilers come to mind but you can write them comfortably in any language.

Probably the biggest sectors where functional programming is used are finance and crypto (which is arguably finance). Some companies use OCaml itself, other companies might use other languages like Haskell where OCaml knowledge would be valuable.

You can see a list on the OCaml website of companies using it, or read some success stories (https://ocaml.org/industrial-users).

The trading firm Jane Street is *the* big OCaml shop, they have a great podcast about all their tech.

(It's one of three programming podcasts I consistently listen to these days, the others being On The Metal and Developer Voices.)
