I don't fully agree with all of the reasoning, but it's a reasonable position to stake.
In Roc – A fast, friendly, functional languageAbsolutely! More details: https://github.com/roc-lang/roc/blob/ad5ed57c4202f847cf9e215...
In Roc – A fast, friendly, functional languageHaving 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#...
In Roc – A fast, friendly, functional languageOops, that's a bug - just opened an issue for it: https://github.com/roc-lang/roc/issues/6027
Thanks for pointing it out!
In Roc – A fast, friendly, functional languageWow, this is depressing to read. :(
5 years ago I was upset and posted a comment that was unfairly harsh to another commenter. I apologized at the time, and I meant it. I definitely should not have made the harsh comment that I did. It was wrong. There's no excuse for my having written it.
There are a lot of people working on Roc other than me. I'm not even the top committer anymore. [0] I hope you can find it in your heart to give their work some consideration, if not mine.

In Roc – A fast, friendly, functional language> How would a user interface written in a functional language look?
Maybe you're not aware of Elm?
https://elm-lang.org
Elm is really functional, unlike the likes of React that are just partially, kind of functional.
There's an attempt at bringing Elm to the desktop, the Roc language... here's an UI example written in Roc:

In Current issues with the Qt project from the outside looking inWhat are your thoughts on the direct descendant, Roc? [0] I know it's pre v0.1 so maybe you don't have any, but as a fellow Elm lover it seems pretty compelling on the surface albeit less directly frontend-dev focused.

In Why and how we retired ElmYou are not alone. The other day I was checking out a new programming language and the author rewrote the unsafe rust part to zig: https://github.com/roc-lang/roc/blob/main/FAQ.md#why-does-ro...
In Zig as an alternative to writing unsafe RustRoc is a new programming language written in Rust (and some Zig).

In Ask HN: What are some good examples of Rust code bases to read and learn from?Check out Roc[0][1] by Richard Feldman; it's early-stages (perhaps earlier stages than Elm?) but from everything I've seen it looks a bit like a spiritual successor to Elm, though focused more on native applications (but still seems to have its sights set on webassembly support too)
