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.

Steel Bank Common Lisp
> both are dynamic languages with types added later in?
Common Lisp has always had types and type declarations (e.g. `the` in the hyperspec[1]) as it's part of the specification. It was not added later as far as I know.
However, `declaim` and `declare` were left very underspecified so they tend to be very implementation-specific, though there are libraries that make types more portable[2][3].

LISP as a learning tool
From python in lisp I want the convenience for quick scripting, which lisp doesn't have by default but of course it can be added. For example for let's you easily iterate over lines of a file or files in a directory, or anything else you add. serapeum add's convenient syntax for hashmaps (dict and @), and threading macro and plenty of utility functions, defclass-std does the boilerplate of :initarg and :accessor for you for the common cases of class declarations.

Compile-time exhaustiveness checking in Common Lisp with Serapeum
Serapeum is an excellent CL library, with lots of utilities. You should check it out. It provides a case-like macro, to use on enums, that warns you at compile-time if you handle all the states of that enum.

looking for Advent of Code Tips
Since Alexandria was mentioned may I mention Serapeum as well. Don't know if it's needed for AoC but it may be worth a look. Serapeum seems to get not enough mentions/ attention IMO.

Common Lisp intermediate book recommendation
Re: libraries; I'd like to mention serapeum which contains a ton of general purpose utilities.

SICL: A New Common Lisp Implementation
I consider Serapeum to be a revamp of the Common Lisp standard: https://github.com/ruricolist/serapeum/blob/master/REFERENCE.... This provides a bunch of new features and idioms including ideas borrowed from newer languages like Clojure.
Great example of "growing a language" as a long-term evolutionary process that doesn't require changing earlier specifications in incompatible ways.

Arena Allocation in SBCL
Based on the commit message [0], and the references to "user code" in this document, my guess is that user programs have or will have access, but it's not finalized enough to be documented.
That being said, I suppose if you're developing an internal API for a compiler/interpreter, your "users" could be other parts of the project rather than language users.
