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.

There is a project that achieves something like this, and quite nicely I think, worth checking it https://github.com/Hirrolot/interface99

Pretty-Printable Enumerations in Pure C
I agree; I would especially not recommend abusing macros throughout an application codebase too much. Conceptually, Metalang99 is more of a (sub)language than a library, which also adds some entry barrier. Ideally, I see the application of Metalang99 being used "behind the scenes", e.g., encapsulated in separate code files/libraries such as Datatype99 and Interface99. This is what I (mostly) do in SmolRTSP.

Comparing Golang and Interface99
There are also some differences. Golang, for example, can resolve interface methods at run-time, whereas Interface99 constructs virtual tables statically. Interface99 allows default implementations; Golang doesn't. And, of course, Interface99 mandates placing impl(MyIface, MyType), whereas Golang uses a.k.a. duck typing for interfaces (interface implementations are indistinguishable from ordinary methods). Also, when you would use embedding in Golang, such as this:
I think your github repo link is broken. Here's a working link.

lipstick: a Rust-like syntax frontend for C
I've done something similar with Datatype99 and Interface99. They are like a macro eDSL that compiles to C. The first one features algebraic data types, the second one features interfaces.

Any alternative to vala?
If you need a bit more high-level constructions, you can use the Datatype99 and Interface99 libraries. The former provides polymorphism over data, the latter -- over behaviour (I am the creator of these libraries).

Is it possible that you could benefit from "a better C"? If so, I'd love to hear your take on Crystal, and the recent announce on Interface99.

Comparing interfaces: Rust and Interface99

Why do lifetimes need to be leaky?
No, you don't. Existential proof: mrustc ignores lifetimes. Just flat out simply ignores. It changes some corner-cases related to HRBT, yet rustc compiled by mrustc works (that's BTW mrustc exist: to bootsrap the rustc compiler).

I think C++ is still a desirable coding platform compared to Rust
Incidentally C++ is the only way to bootstrap rust without rust today.

Rust – Faster compilation with the parallel front-end in nightly
Well, there is mrustc[0], a Rust compiler that doesn't include a borrow-checker, so it's possible to compile (at least some versions of) Rust without a borrow checker, though it might not result in the most optimized code.
AFAIK there are some optimization like the infamous `noalias` optimization (which took several tries to get turned on[1]) that uses information established during borrow checking.
I'm also not sure what the relation with NLL (non-lexical lifetimes) is, where I would assume you would need at least a primitive borrow-checker to establish some information that the backend might be interested in. Then again, mrustc compiles Rust versions that have NLL features without a borrow-checker, so it's again probably more on the optimization side than being essential.

Forty years of GNU and the free software movement
> Maybe another memory safe language, but Rust has severe bootstrapping issues which is a hard sell for distros that care about source to binary transparency.
It is possible to bootstrap rustc from just GCC relatively easily, although it's a little bit time consuming.
You can use mrustc to bootstrap Rust 1.54: https://github.com/thepowersgang/mrustc
And from then you can go through each version all the way to the current 1.72. (Each new Rust version officially needs the previous one to compile.)

Stop Comparing Rust to Old C++
There are three. The official one, mrustc (no borrow checker, but can essentially compile the official rustc) and GCC (can't really compile anything substantial yet). Only rustc is production-ready though.

Can I make it so that only the newest version of Rust gets installed?
That probably depends on what you mean by problematic. Having an ever increasing chain of dependencies isn’t the most desirable situation so there has been some work to trim the bootstrap chain. In 2018, when the blogpost I linked above was written, mrustc was used to bootstrap rust 1.19.0; now mrustc can bootstrap rust 1.54.0 so the chain to recent versions is much shorter than if all those intervening versions back through 1.19.0 needed to be built. https://github.com/thepowersgang/mrustc
