Having a play with Gleam right now. Roc's managed effects sounds interesting, maybe Gleam could layer something similar atop Erlang's OTP? Right now, outside a database, it's not clear to this newbie how state is meant to be managed in Misty, the Gleam web framework I am kicking the tyres of. If I can be bothered, I was seeing myself having to delegate state management to a separate process (which Gleam seems to support well, but it's work I didn't anticipate and I am at this stage only playing).

Edit: related to state management, the "platform" concept looks interesting too https://github.com/roc-lang/roc/wiki/Roc-concepts-explained#...
