C# is good too. If you havent heard of lobster you should look into it.

Rust

With no context, this could be an honest attempt to learn about different tools, a thinly veiled set-up to promote a specific language, or an attempt to stir up drama. I can’t tell which.

It’s curious how such specific conditions are embedded into the question with no explanation of why, yet “memory safe” is included among them without specifying what kind of memory safety.

As others have said, Haskell and Rust are pretty great. A language that hasn’t been mentioned that I REALLY want to catch on, though, is Unison.

Scala 3 native. If the compiler was faster I’d be even happier. Curious to try Ada

declare(strict_types=1)

Rust and Haskell (I think Haskell counts)

That is a very specific subset

🦀

Rust for now, by a wide margin. But I’m following other languages that I think have the potential to surpass it, including Vale (promises way more than it delivers currently), Koka, Hylo, maybe Lobster.

Python with MyPy.

(Almost any language can meet those criteria, with enough shenanigans.)

Rust.

Ada, hands down. Every time I go to learn Rust I’m disappointed by the lack of safety. I get that it’s miles ahead of C++, but that’s not much. I get that it strikes a much better balance than Ada (it’s not too hard to get it to compile) but it still leaves a lot to be desired in terms of safe interfacing. Plus it’s memory model is more complicated than it needs to be (though Ada’s secondary stack takes some getting used to).

I wonder if any other Ada devs have experience with rust and can make a better comparison?
