Is the previous plan for adding effects in OCaml 5.1 still in place? I am very excited not only for the native parallelism that's coming in 5.0 but also about the effect handlers! I am sure many others are looking to start creating very interesting things with them, e.g. Rust-alike async capabilities or Erlang's preemptive green threads / actors runtime.

5.00 (the first release with multicore) will include effects! More info: https://discuss.ocaml.org/t/multicore-ocaml-september-2021-effect-handlers-will-be-in-ocaml-5-0/8554 https://discuss.ocaml.org/t/multicore-ocaml-september-2021-e...

  Oh. I haven't followed lately. Thanks a lot for the updated info! Really looking forward to what the community will build with OCaml 5.00! IMO it will shoot the language straight into the mainstream and I can't wait. OCaml is applicable for like 90% what's out there, including as a Python replacement. And its syntax is often much terser than Rust (although the higher-level typing constructs can be confusing to read). After that, all that's left is a tool like Elixir's mix or Rust's cargo and the language is basically not only in the 21st century but much farther than many others! Looking forward to it.

    > all that's left is a tool like Elixir's mix This so much. Mix is so pleasant to work with, but getting an OCaml project off the ground requires messing with dune + esy if you want consistent and isolated package management. It's a massive pain.

  Yes, but note the absence of syntactic support. Effects will be usable for writing libraries and experimentation, but routine use won't be very ergonomic until a later release.

    Considering the hard part of effects is implementing them at the language level, deferring on syntax is a good problem to have.
