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.

Much of Go's unusual syntax comes from Oberon-2 (though Robert Griesemer, who worked on Object Oberon). Video timestamp is 17 minutes, 50 seconds.
Some time ago I ported Wirth's Project Oberon compiler to Go, and here's a Project Oberon emulator in Go.

A Discussion of Oberon
If you like Oberon and Go, here are two projects I did last year:
- A port of Peter De Wachter's Project Oberon RISC emulator to Go: https://github.com/fzipp/oberon
- A port of Wirth's Project Oberon RISC compiler to Go: https://github.com/fzipp/oberon-compiler

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.

Project Oberon
The Oberon channel has several videos of Oberon in action,

While Oberon was quite cool, people should also learn about its Xerox influence,

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.

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
What are some alternatives?
a2 - Active Oberon System (AOS), aka A2, and Bluebottle OS
oberon-riscv - Oberon RISC-V port, based on Samuel Falvo's RISC-V compiler and Peter de Wachter's Project Norebo. Part of an academic project to evaluate Project Oberon on RISC-V.
