I talk about FLAME outside elixir in one one of the sections in the blog. The tldr; is it's a generally applicable pattern for languages with a reasonable concurrency model. You likely won't get all the ergonomics that we get for free like functions with captured variable serialization, but you can probably get 90% of the way there in something like js, where you can move your modular execution to a new file rather than wrapping it in a closure. Someone implementing a flame library will also need to write the pooling, monitoring, and remote communication bits. We get a lot for free in Elixir on the distributed messaging and monitoring side. The process placement stuff is also really only applicable to Elixir. Hope that helps!
