His Lisp library for performing extremely fast, extremely high-precision arithmetic https://github.com/stylewarning/hypergeometrica sounds intriguing.

Another thing to try out some day.

From the author's description:
1. Flexible templates
CL-Project supports more parameters to embed, by using CL-EMB to represent the skeleton files (See "cl-project/skeleton/").

2. One package per file style (Modern)
A modern CL project should be in accordance with some rules. For instance, one file must have one package in it.

3. Recommends unit testing
Modern projects should have some unit tests. CL-Project generates a system for unit testing, so you can begin writing unit tests as soon as the project is generated.

His static site generators https://github.com/eigenhombre/weeds and https://github.com/eigenhombre/organa look interesting too.

require-module sounds interesting.

"What if documentation really lived in the code?

Docstrings are already there. If some narrative glued them together, we'd be able develop and explore the code along with the documentation due to their physical proximity.

With the simplistic tools provided, one may emphasize the narrative as with Literate Programming, but documentation is generated from code, not vice versa, and there is no support for chunking.

Code is first, code must look pretty, documentation is code."

Fe[nl]ix explains his approach to maintain a version number for Lisp systems.

Polynomial root finder for {dm,hp}42s using Laguerre's method. Found on https://forum.swissmicros.com/viewtopic.php?p=20091#p20091
The Emacs tools for {dm,hp}42 code on https://richmit.github.io/hp42/hp42s-meta.html and the
