Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

compile time memory management models
I'm trying to implement compile time memory management in my language siko. My idea is to completely hide it from the user, they can only use immutable values and the compiler is trying to figure out a way to optimize it in the background. The design/implementation is good enough to self host the language and now the compiler is written in siko. This also serves as a giant test suite:)

Multitasking, parallel processing, and concurrency in Swift
Or give up and erase all the type information by saying `throws Exception` or `throws Throwable`.
Genericizing throws in particular was tried in Midori [2] and worked out really well (by report). In addition, several less-than-completely-obscure languages are starting to experiment with the algebra of effects in general (as opposed to error handling in particular). Pony (https://www.ponylang.io/), OCaml (https://ocaml.org/manual/5.2/effects.html) and others are experimenting with bringing what Koka (among others; https://koka-lang.github.io/koka/doc/index.html) to the masses.

The problem with general purpose programming languages
For example, the actor's model is not used by a lot of languages, Pony (https://www.ponylang.io/) and Elixir are the only ones that I know, but they address the concurrency problem quite well, while it's a pain to deal with in other languages at large scale.

Found a language in development called Vale which claims to be the safest AOT compiled language in the World (Claims to beSafer than Rust)
And that last point is critical. If the language flatly can't represent some concepts it uses, they have to be implemented somewhere else. I had a similar discussion with a proponent for Pony once- the language itself is 100% safe, and fully dependent on C for its runtime and data structures. One of Rust's core strengths is being able to express unsafe concepts, meaning the unsafe code can expose a safe interface that accurately describes its requirements rather than an opaque C ABI. Vale doesn't seem to do that.

The Rust I wanted had no future
"Exterior iteration. Iteration used to be by stack / non-escaping coroutines, which we also called "interior" iteration, as opposed to "exterior" iteration by pointer-like things that live in variables you advance. Such coroutines are now finally supported by LLVM (they weren't at the time) and are actually a fairly old and reliable mechanism for a linking-friendly, not-having-to-inline-tons-of-library-code abstraction for iteration. They're in, like, BLISS and Modula-2 and such. Really normal thing to have, early Rust had them, and they got ripped out for a bunch of reasons that, again, mostly just form "an argument I lost" rather than anything I disagree with today. I wish Rust still had them. Maybe someday it will!"
I remember that one. The change was shortly after I started fooling with Rust and was major. Major as in it broke all the code that I'd written to that point.
"Async/await. I wanted a standard green-thread runtime with growable stacks -- essentially just "coroutines that escape, when you need them too"."
I remember that one, too; it was one of the things that drew me to the language---I was imagining something more like Pony (https://www.ponylang.io/).
"The Rust I Wanted probably had no future, or at least not one anywhere near as good as The Rust We Got."
Almost certainly true. But The Rust We Got is A Better C++, which was never appealing to me because I never liked C++ anyway.

How long until Rust becomes mandatory, and use of any other language opens the developer up to Reckless Endangerment charges
Pony or bust.

Universal parameter passing semantics
If you have a value in mutable storage, and want to treat it as an immutable parameter without copying it first, you will need to provide some way to guarantee that it won't be mutated while being treated as immutable! There doesn't seem to be a definitive best way to do that (although the likes of Pony make a try at it).

Virtual Threads Arrive in JDK 21, Ushering a New Era of Concurrency
The love child of Erlang and Rust exists already: Pony.
https://www.ponylang.io
It really is the best of both languages... unfortunately, the main supporter of Pony seems to have stopped using it in favour of Rust though :D.
But if that's really what you want, Pony is your language. It definitely deserves more love.

Why Turborepo is migrating from Go to Rust – Vercel
You can actually try to have a magic language which "does not ignore decades of PL research" but you are likely to get either something broken or a project that is likely not going to release in our lifetime.
