It’s such a nice language, too. It’s too bad it doesn’t get more attention. I know someone who regularly runs a couple of utilities written in Haskell, but they’re the only Haskell code in his entire organization. It’s a shop that has C, C++, Rust, JavaScript, TypeScript, Python, and Go in production, Java in legacy production, and has half a dozen other languages in production support situations. Haskell has not caught on there, though.

I’m aware a few companies use primarily OCaml just as a few use primarily some form of Lisp. It’s just that some of these really nice languages don’t see as much use as they could.
