I believe Fly.io deploys some Gleam in prod. I tried playing with Gleam for a bit, but I got stuck trying to make the Actor Model make sense. It’s Gleam’s solution to mutable state, inherited from Erlang and the BEAM. It takes so much code just to emulate a simple, mutable Map. I liked Rust’s middle ground with `mut` in function defs.
