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.

What is the point of the if __name__ == "__main__":, i.e. why use a file as both script and module?
The Lissp transpiler incrementally compiles and executes each top-level form to Python. It needs to do this in case there's a macro definition that might affect the compilation of a subsequent form. If it's only executing definitions, this is harmless, but if you want to precompile the main module, it needs the guard, or the side effects will happen too.

What's the most hilarious use of operator overloading you've seen?
If you want Python to be as customizable as Lissp, check out Hissp (and Hebigo).

Want cleaner code? Use the rule of six
Python's lambdas can have as many lines as you want. Just wrap parens around it. Hissp uses this form as a compilation target. Its REPL shows the Python compilation. Play around with it til you get it: https://github.com/gilch/hissp

Is ECMAScript really a dialect of Lisp?
The original Lisp's S-expression syntax was just supposed to be an intermediate language used by the compiler when processing the real language based on M-expressions, which kind of never took off. Numerous alternatives to S-expressions have been proposed, and some retain homoiconicity, another feature diagnostic of a Lisp (and one that ECMAScript lacks). For example, see Hebigo's readme, which shows a direct correspondence between its Python-like syntax and that of Hissp's default reader (Lissp), which uses the S-expressions. Julia can also be written in S-expressions, but this usually only used in macro definitions.

Land of Lisp
I think LoL is too CL-specific. If you know both languages first, you can pretty much translate, but since they'd be trying to learn Lisp in the first place, this is a bad idea.
On the other hand, [Hissp][1] has a pretty good tutorial for anyone coming from a Python background.

Interesting or distinctive lisps?
Hebigo: a whitespaceLisp isomorphic to Hissp that looks like Python.

what math is required?
It might be useful to maybe look at the Vulkan.hpp examples since you can do the same in about 200 lines of code. https://github.com/KhronosGroup/Vulkan-Hpp/blob/main/samples/15_DrawCube/15_DrawCube.cpp
- Vulkan-Hpp now provides C++20 module interface file

How do you guys organize everything?
Wow that library looks amazing, I'll definitely be using it. Bonus that it's official from the Khronos Group. https://github.com/KhronosGroup/Vulkan-Hpp
-
An idea to ease wrapping C libraries in C++.
Even auto-generated c++ wrappers like vulkan-hpp require lots of manual maintenance.
-
Anybody know why V-EZ has not been updated in 5 years?
Ultimately I went with vulkan.hpp RAII bindings, even though that way also has some learning curve and I couldn't find any documentation other than the RAII programming guide. It's great for getting started, but could use a complementary auto-generated API doc. There are also decent programming samples, which really suck for getting started, but otherwise do a good job of presenting concepts they focus on. Putting the available resources together I was able to get a project going in two weekends.

Using enum classes as bitmasks
This is exactly how the official Vulkan C++ API, Vulkan-Hpp does it. For the precise example mentioned in the blog post:

Recommendations on how to start a small Vulkan project
Or the vulkan.hpp RAII samples would be a good place?
-
What's the most hilarious use of operator overloading you've seen?
For a real-life example: consider the vk::raii namespace of Vulkan-Hpp, where the developers have posted examples. The vk::raii::su namespace has a bunch of free functions that one might think are associated with a Vulkan instance/object (in fact, the Vulkan Tutorial does implement them as member functions), but they are much nicer when used as pure functions. It keeps the class/struct definition itself nice and clean.
