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.

Future of high-level languages
Sum types and pattern matching have already been hacked together in a preprocessor macro in C; see https://github.com/Hirrolot/datatype99.
- So far there is no evidence that Rust adds any value here. And if C is missing certain features, they can be added.
-
Does C have an equivalent to an algebraic data type?
It does not. There are people who have implemented such constructs in C code however, for example: https://github.com/Hirrolot/datatype99

Memory Management Reference
Nice reference but with some strange bits:
> Algebraic data types are usually represented using a heap. Because of their non-uniformity, algebraic data types are more difficult to scan.
Using a heap??? We can represent ADTs using stack as well, that's what we usually do in C and Rust.
Shameless plug: https://github.com/Hirrolot/datatype99 (a library of mine that generates type-safe ADTs for pure C99).

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.

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).
-
Syntatic Sugar that compiles to C
OP, you might find datatype99 and its sibling projects interesting, though they mostly leverage the C preprocessor without going all the way towards defining a new language.
-
AST Implementation in C
You can use Datatype99 to represent your AST tagged union conveniently.
-
Rust for Linux Redux
Compared to plain C, you have ADTs which help from day to day programming. You can bring them to C (https://github.com/Hirrolot/datatype99) but I don't know if the Linux guys would allow it.

C2rust: Transpile C to Rust
Back in the day there was also Corrode: https://github.com/jameysharp/corrode
-
lipstick: a Rust-like syntax frontend for C
Some intersection with https://github.com/jameysharp/corrode in theory right? Maybe it's saner actually to start with corrode-to-lipstick (there has to be a good project name here) and then it's perhaps easier to turn lipstick into safe Rust?
