Absolutely. Everyone uses OCaml at Jane Street; pretty much everything at Jane Street is OCaml. If an OCaml version of something doesn't exist, there's a decent enough chance that they'll write it themselves rather than resort to a non-OCaml solution.

Like I said, my information might be a hair out of date, but it's first-hand.

Gotcha. Mine is just some old blog posts and a long talk from the guy that got OCaml started. Nothing like your actual first person experience. Thanks for adding!
