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.

Is there a type-theoretical difference between generics and compile-time metaprogramming?
I am not super knowledgeable about this, but I think you might find Type Systems as Macros interesting. There is also the in-development language Hackett which uses the approach described in the paper to unify Racket style macros with a Haskell style type system.
- Hackett is a statically typed, pure, lazy, functional programming language in the Racket language ecosystem

Rebuilding Emacs from scratch. What would you do differently?
I agree. I've been searching for solutions for a while. A few choices: - Common Lisp Coalton, very similar to Haskell. - Hackett, a Haskell-like DSL implemented in Racket. Licensing would be an issue, so it would have to be ported to Guile Scheme if you want to build an Emacs out of it. This is not easy since it takes advantage of several Racket-specific language features. - Shen, which can be built on top of Common Lisp, Scheme, Racket, or even Emacs Lisp. The drawback is that it is a fairly cryptic language, and extending foreign language bindings is not well documented. You would basically have to program the entirety of Emacs from scratch - PreScheme is a statically-typed (Hindley-Milner family) subset of Scheme that compiles to C. Originally written to build the Scheme-48 compiler, it is being ported to Guile. Not production read yet. - Zile is an editor engine built on Guile 2.0. But there is no static typing or algebraic data types, it is simply a replacement for Emacs written in Scheme from the ground-up. It needs to be ported to Guile 3.0. Guile 3 has an Emacs Lisp interpreter built-in, but it needs to be developed further before it could run more popular Emacs Lisp applications like Org-Mode or Magit.

Asked ChatGPT to explain Haskell to me in the style of Edgar Allan Poe, and the answer was beautiful.
Meh. As my final part in this exchange I will leave this here, conclusion are left to the reader: https://lexi-lambda.github.io/hackett/

is there an alternative to template haskell?
My dream is something like Hackett, but alas, Alexis didn't have time to continue it. Someday ...
- What are the design principles of raco and the Racket ecosystem?
-
Is there any way to use typed racket and lazy racket together?
The documentation says it does: https://lexi-lambda.github.io/hackett/
-
Unpopular opinion: actually, Emacs does fulfill the tenets of the UNIX philosophy
But we can always import Coalton, or Hackett, or miniKanren into our Lisp program if we need it.

Honest question: why is Haskell not a lisp / built on s-expressions?
This doesn't really answer your question but you may be interested in checking out https://lexi-lambda.github.io/hackett/ by u/lexilambda.

How do you typecheck a macro?
Extremely difficult, but you can do some cool stuff with macros if you do it. Have a look at Alexis King's "Hackett" language for a cool example: https://lexi-lambda.github.io/hackett/
