“Switching over to OCaml I found wonderful - I had not worked with FP before and I found it delightful, it kind of cured my programming burnout a bit”

“the important stuff then slow careful crafted rock solid and lightning fast ocaml. feels like this is the way.”
POSITIVE · performance · Hacker News · 2026-07-09
“incredibly painful working with OCaml and dune on Windows, unfortunately. Docs are insufficient and there is little information online :/”
NEGATIVE · documentation · Hacker News · 2026-06-09
“it became ugly quickly, because I had to use `ocamlfind` and `ocamlc`, and provide a list of all packages to include and so on”
NEGATIVE · ease of use · Hacker News · 2026-06-09
“I find the development cycle with ocaml to be nicer in several ways compared to rust”
POSITIVE · ease of use · Hacker News · 2026-05-15
“OCaml (especially OxCaml) sits at a really good point on that curve”
POSITIVE · features · Hacker News · 2026-05-15
“I have done some Ocaml, quite a bit of embedded systems, and these days I have to waste the years doing web development. Where do I have to call to be considered for doing OCaml embedded systems?”
POSITIVE · Hacker News · 2026-05-15
“OCaml was running almost the entire data processing chain, including spectroscopy, image corrections, retrievals and post-retrieval ad hoc bias corrections, as well as simulations”
POSITIVE · performance · Hacker News · 2026-05-15
“The whole processing and simulation toolchain was also written in OCaml.”

“ocaml is more powerful than rust for enforcing this sort of type safety, because you have gadts that give you more expressive power, and polymorphic variants and object types (record row types) that give you more convenience. and the module system and functors of course.”
POSITIVE · features · Hacker News · 2026-05-03
“a strong OCaml-like type system which I've used before (better than TypeScript even in some cases)”
POSITIVE · features · Hacker News · 2026-03-08
“Ocaml alleged frictions were always widely overstated. When I was writing Ocaml professionally 15 years ago, there was no dune and no opam and it was already fairly easy to use the language.”
