OCaml got experimental algebraic effects in version 5.0 (December 2022). Here is a tutorial: https://github.com/tanelso2/ocaml-effects-tutorial https://github.com/tanelso2/ocaml-effects-tutorial Also from the tutorial: "Unlike Eff, Koka, Links, and other languages that support effect handlers, effects in Multicore OCaml are unchecked currently. A program that does not handle a performed effect fails with a runtime error."
