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.

Enhancing development with REPLs - A practical guide
Alongside the wide range of gems around the pry REPL we have pry-rescue that allow us to start a debugging REPL as soon as a test fails, that way we can investigate and fix it before waiting for all the other tests to run:
- Debugging Ruby application running in docker with VS code
-

Add the pry-rescue gem.

On repl-driven programming
Breakloop: a quick Google shows that pry-rescue and web-console exist, which are pretty much it

The thing is, if you start with Common Lisp, it's pretty easy to write a DSL that adds the constraints and provides the guarantees that you need. [..] Maybe all I had to do to turn CL into Haskell is implement the Hindley-Milner algorithm.

Hell Is Other REPLs
I used to use CL quite a bit, but have since abandoned it for Haskell, so I'm a bit biased.
There's a number of issues with that:
- I'd be missing all the optimizations that can be performed due to purity.
- There's more to Haskell's type system than just vanilla Hindley-Milner, and the implementation of it isn't particularly trivial. https://github.com/stylewarning/coalton is the closest thing and it's still missing a large amount of the type system.
- Doing the implementation would be a significant amount of work to get it to integrate well with the language, and it would be a layer tightly glued on top instead of integrated with the language.
- A major part of Haskell is the standard library, a good chunk of the semantics of Haskell people use on a day to day basis, like monads and etc, are a part of the standard library.

Six years of professional Clojure development
This looks like something Common Lisp does better, however I have too little Clojure experience to compare. CL (and SBCL in particular) does "good enough" static type checks, it throws warning at compile time (when we compile one function with a keystroke). We can also precise our function types gradually. It isn't a HM type system (Coalton[1] could be it) but it's already great (compared to no compile-time types at all).
Oh, about interactive development: that's sure, CL shines here. Objects get updated (lazily) after a class change, we can install Quicklisp libraries without restarting the image, etc. It's very smooth.
