An implementation of ANSI Common Lisp written in C.
If I find the time, I would like to find answers which allow to add information to the table on https://www.cliki.net/Common%20Lisp%20implementation

"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."

Lots of links to interesting projects.

SC4 is a secure communications system specifically designed for (relatively) easy auditability by way of a ruthless commitment to simplicity. SC4 provides the functional equivalent of PGP from the end-user's point of view, but implements it in two order of magnitude less code. The cryptographic core of SC4 is Daniel J. Bernstein's TweetNaCl library (<800 LOC). On top of this we have a variety of UI implementations ranging from 1000 to 5000 LOC. One of these has completed a formal audit to date.
