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.

ClojureRS – Clojure interpreter implemented in Rust
Thanks for sharing! I think these restarts could definitely be implemented as a library in Clojure with the help of a coroutine library like https://github.com/leonoel/cloroutine#guides

GitHub - leonoel/cloroutine: Coroutine support for clojure
Do you mean the example here https://github.com/leonoel/cloroutine/blob/master/doc/01-generators.md , with the `*tail* binding? It took me a long time looking at it to finally grok it, and it's really hard to explain in English but basically when the coroutine comes across one of these symbols that are "breaks" (in our case, "yield" is such a breaking symbol), then it will pause the coroutine, and actually call what the symbol points to (the implementation of "yield"), which returns (cons x *tail*), and keep in mind that it is all run within a recursive call to gen-seq where *tail* is bound to a lazy-seq of the remainder of the generator (binding [*tail* (gen-seq gen)] (gen)), it's pretty confusing but yeah just have to stare at it for a long time I think haha.

CLJ-2555: clojure.core/iteration · clojure/clojure@e45e478
I think Clojure is really missing python/js-style generators, like what is implemented in https://github.com/leonoel/cloroutine/blob/master/doc/01-generators.md

Real-life use cases for CLJS macros
The next level up is core.async go blocks which compile your AST to a state machine. Also see cloroutine which also compiles the AST to a state machine or something, one of the tutorials uses cloroutine to add async/await to Clojure.

Common Lisp Style Conditions+Restarts in Clojure
Coroutines are a more general concept, and can be used to implement conditions/delimited continuations. There’s an example in their docs.

What's the value proposition of meta circular interpreters?
I've tried researching this myself and can't find too much. There's this project metaes which is an mci for JS, and there's the SCI module of the Clojure babashka project, but that's about it. I also saw Triska's video on mci but it was pretty theoretical.

Adding Dependencies on Clojure Project the Node Way: A Small Intro to neil CLI
Created by the same guy who created babashka which is a way to write bash scripts, node scripts, and even apple scripts using Clojure. A very proficient and influential developer in the Clojure community. This is how borkduke's neil helps us:

Not what you asked for but there is Babashka for scripting in Clojure.

Critique of Lazy Sequences in Clojure
Clojure's lazy sequences by default are wonderful ergonomically, but it provides many ways to use strict evaluation if you want to. They aren't really a hassle either. I've been doing Clojure for the last few years and have a few grievances, but overall it's the most coherent, well thought out language I've used and I can't recommend it enough.
There is the issue of startup time with the JVM, but you can also do AOT compilation now so that really isn't a problem. Here are some other cool projects to look at if you're interested:

Are there any languages (that are in common use in companies) and higher-level that give you the same feeling of simplicity and standardization as C?
I've enjoyed babashka for scripting; which is close enough to clojure to allow using some/many libraries; but (probably) not for embedding.
What are some alternatives?
zio-schema - Compositional, type-safe schema definitions, which enable auto-derivation of codecs and migrations.
janet - A dynamic language and bytecode vm
farolero - Thread-safe Common Lisp style conditions and restarts for Clojure(Script) and Babashka.
malli - High-performance data-driven data specification library for Clojure/Script.
core.async - Facilities for async programming and communication in Clojure
joker - Small Clojure interpreter, linter and formatter.
ClojureRS - Clojure, implemented atop Rust (unofficial)
nbb - Scripting in Clojure on Node.js using SCI
clojure-scheme - Clojure to Scheme to C to the bare metal.
clojure-lsp - Clojure & ClojureScript Language Server (LSP) implementation
await-cps - async/await for continuation-passing style functions
racket - The Racket repository
