The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

Interactive animations
Yeah, that project is pretty much at the bottom of my list, unfortunately. My top projects these days are mgmt, klister, recursion-schemes, and hint... And that's already too much!

Rust Tests Itself (Kind of!)
case is a special form, ie a bit of core syntax, but, interestingly, data is not. (It is presumably a macro; typechecking is actually done as a part of macro expansion.) The syntax remains pretty uniform. Or, in Klister, type ascription is done via normal S-expression syntax with a form called the, as (the $type $expression); again, the syntax is uniform.

GHC Hacking
Shameless plug: we don't have that problem in Klister, because our equivalent to main is a run macro which runs an IO action, and your alternate prelude can define its own run macro which expects an IO action from your alternate prelude.

What's the preferred way of getting powerful lisplike macros on Haskell?
Klister is very similar to Hackett, but implemented in Haskell instead of Racket, and my most recent PR is from 20 days ago, if that's the metric which counts for you. Still very much of a WIP though.

How do you typecheck a macro?
You might be interested in Klister: https://github.com/gelisam/klister

Using defmacro's &environment argument to implement Racket's hygienic macro expansion system?
I've now also found an implementation for klister, which is meant to interleave type checking with macro expansion.

Haskell doesn't have macros
In Klister, which already has Scheme-like macros and Haskell-like types (polymorphism, algebraic types and higher-kinded types, but not yet fancier types like RankNTypes and GADTs), our plan to get the best of both worlds (lexical syntax and typed ASTs) is to separate parsing from macro evaluation. That is, users write their programs using the surface syntax of s-expressions, parsers parse those into typed ASTs, and macros are typed by the type of the ASTs they receive as input and produce as output. At this stage this is only a research idea, I don't know if that's going to work out yet, but I hope so!

Kinds and Higher order types use cases?
As for uses of kinds in general, I'm using them a lot in Aith. Except that, instead of using higher kinds I'm parameterizing my Type to allow for fancier classification then just "this is a type". I'm using kinds for

Why is there no simple C-like functional programming language?
Aith is another new one.

Resources to build an interpreter or PL in Haskell?
https://github.com/Superstar64/aith is also an interesting language, with substructural typing. The creator is also in the discord server if you have any questions

Type Annotation Decoration and Avoiding Regeneralization
In Aith after doing hindley milner type checking, I want to annotate my ast with type annotations for several reasons:

How do you typecheck a macro?
It depends on how powerful you want your macros to be. In aith, my macros are just a compile time lambda calculus. My macros can only generate values or other macros, this limits them to being no more powerful then what you can normally do with functions but it (will when my language is usable) let me write code that I know will be inlined and edsls that compile into fast code. With these limitations I can completely type check macros ahead of time (because they are just like funcitons) and I can also use my kind system to prevent macro types from leaking out into normal ones.
What are some alternatives?
