One sort-of exception is Erlang (and anything else that runs on the BEAM vm, like Elixir). It doesn't match Alan Kay's vision exactly, because the message passing is done a bit differently (for example it's asynchronous), but creator Joe Armstrong called it something like "the best of functional programming and OOP". If you come from C++, Java, or other "OOP" languages, and look at Erlang, it's completely different than what you expect. In Erlang, the "objects" are less like mutable structs and more like functional mini-programs that can create new programs, pass messages, and fail as you would expect. To get some perspective on both of their perspectives, here's "Joe Armstrong interviews Alan Kay": https://www.youtube.com/watch?v=fhOHn9TClXY https://www.youtube.com/watch?v=fhOHn9TClXY

> for example it’s asynchronous Ruby also lets you build programs like this as of 3.0, using Ractor#send / Ractor::receive https://docs.ruby-lang.org/en/master/doc/ractor_md.html#label-Communication+between+Ractors https://docs.ruby-lang.org/en/master/doc/ractor_md.html#labe... It’s still pretty new so a lot of the Gem ecosystem hasn’t caught up yet (e.g. C extensions need to be explicitly opted-in as Ractor-safe), but I built a new “MIME::Types” library replacement with it recently and have enjoyed very few teething issues: https://github.com/okeeblow/DistorteD/blob/NEW%E2%80%85SENSATION/CHECKING%20YOU%20OUT/lib/checking-you-out/ghost_revival.rb#L363 https://github.com/okeeblow/DistorteD/blob/NEW%E2%80%85SENSA...

> Joe Armstrong called it something like "the best of functional programming and OOP". Though IIUC Armstrong only started doing that after others pointed out that it was OOP.
