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.

A quick look at destination-driven code generation
This technique was also described by David R. Hanson in "Code Improvement via Lazy Evaluation", 1980 [1] and "Simple Code Optimizations", 1983 [2].

Ask HN: Why are there no traditional language compilers that target the JVM?
The Oberon programming language is 37 years old. Since it is a memory safe language a compiler for the JVM can be written (with some workarounds), for example see the self-hosting compiler oberonc [0].

Modula-2 and Oberon (2007) [pdf]
If you want to try out only the Oberon language, you might be interested in oberonc [0] an oberon-07 self-hosting compiler for the JVM. There are other several Oberon implementations for different platforms listed here[1]

The School of Wirth
When I benchmarked oberonc [0], an oberon-07 self-hosting compiler for the JVM, it took about 100 ms with a hot VM on a old Intel i5 @ 2.80GHz. That compiler follows the same one-pass compilation approach.

Oberon: The tiniest but richest FOSS HLL and OS you've never heard of
Because of pjmlp's hint I just looked into the repositories https://github.com/btreut/a2 and https://github.com/metacore/A2OS, but didn't find a coroutines module. I'm aware that Active Oberon (Patrik Reali, 2004) includes concurrency, but this is a different language than the one used for System 3.

The Oberon channel has several videos of Oberon in action,

While Oberon was quite cool, people should also learn about its Xerox influence,
"Eric Bier Demonstrates Cedar"
https://www.youtube.com/watch?v=z_dt7NG38V4
Also dive into what happened afterwards, Oberon-2, Active Oberon, Zonnon,...
Active Oberon could be considered quite modern, also makes the distinction between safe and unsafe pointers, which improves the experience for low level coding.
https://github.com/metacore/A2OS
One of the best things about these systems is proving what systems programming with automatic memory management were capable of.
Given Oberon-2's influence on Go, maybe improving Fyne (https://fyne.io/fynedesk/) with something like gRPC for the dynamic experience, could be a possible sucessor.

Leveraging the Go Type System
A couple, you can start here to see how the Active Oberon based OS looked like,

Some links are broken now, because ETHZ no longer hosts the A2 site, however you can get the latest language report at http://cas.inf.ethz.ch/boards/2/topics/1
And the source code and old documents for the original A2 OS at github, https://github.com/metacore/A2OS
