I'd say if you know and like Rust, then Gleam should be easy to pick up but otherwise I'd try Elixir. You can learn most of the language in a few days and be experimenting with BEAM and supervision concepts basically on day one. As a learning exercise I think its worth peoples' time because actors/processes are one of the concurrency models you don't see everywhere but solve interesting problems well.
I don't think that's the case, Rust and Gleam have almost nothing in common beyond having static type systems, and those type systems are very different too.

I think by sentiments like this, people mean if you know unions, records, and pattern matching then you'll more easily pick up another language that has unions, records, and pattern matching.
Right, and I’m explaining that my multiple years of experience teaching and helping newcomers that an expectation of similarity to Rust frequently results in difficulty, and that it is beneficial to downplay any perceived link.
I think a Rust programmer is more likely to prefer Gleam to Elixir, but I don't think there is much link between Gleam and Rust, and I especially do not thing that Gleam should only be considered over Elixir if you are already a Rust programmer.
You said:
>I'd say if you know and like Rust, then Gleam should be easy to pick up but otherwise I'd try Elixir.
This is way too strong and narrow statement. Gleam is statically typed garbage collected language, closer to OCaml than Rust. Elixir if you like dynamically typed instead.
Nah, the gradual angle is not what makes a type system tricky to implement. Plus we have published a few papers discussing how we are typing Elixir and how our approach is sound.
It's very possible that I'm misunderstanding you! I'm mostly just saying that Gleam is very unlike Rust, so if you pick it or avoid it for Rust related reasons you may not be making the most informed decision.
The languages that Gleam is most like might be Standard ML, OCaml, Elm, and F#.
You seem to be interpreting the statements as technical comparisons of the languages, but ch4s3 was (by my read) commenting on the overall ability of a programmer to jump from one language to another.
That is: they aren't similar languages on a technical level, but if you know Rust, you should be able to make the jump to Gleam pretty quickly.
Aye, I am saying that jumping from Rust to Gleam isn't easy because the languages are so different. "How do I do X in Gleam like I would in Rust" is one of the most common categories of support question from newcomers who assumed they were similar.
I use Rust and prefer Elixir over Gleam because Elixir has Lisp-style macros (Gleam doesn't), uses OTP directly, has the fantastic IEx REPL (Gleam has no counterpart), and has Phoenix, the best web framework I've ever used.
