First exposure to gleam here and I'm impressed. I am somewhat puzzled though, as I don't see any references to otp/actor examples on their "language tour", which I would have guessed is the main use case coming from Erlang for at least the server side. Are they deemphasizing otp since it targets both Erlang AND JavaScript? Presumably for the gains of "one lang" across the stack like node/deno provides?
Looks like it is an external library[^1]. Readme states it is experimental and lists some limitations.
