To wit: I have just released a new version of my Cozenage Scheme interpreter. What is Cozenage?

Cozenage is a Scheme-derived, Lisp-like programming language written in C, designed primarily as an educational project and exploratory implementation. It provides a small, expressive core language and is extended through a growing standard library of dynamically loadable modules.

You should almost certainly install this program, and start writing some Scheme code! Scheme is awesome!

You can clone from GitHub, or download release tar and zip files:

There is documentation available here:

https://darrenkirby.github.io/cozenage/

Honestly though, I don't really know what I'm doing. I'd really just like some folks who are not me to run this, and try to daylight some bugs as I'm sure there are many!

Did you know you can pass < or > directly into sorted(by:) as closures? This technique leverages Swift's functional programming capabilities for more expressive and concise collection sorting.

pub fn new(value, min, max) -> {
Ranged(
value: int.clamp(value, min:, max:),
min:,

pub fn set(current: Ranged, to new: Int) -> Ranged {
Ranged(
value: int.clamp(
new,
current.min,
current.max,

min: current.min,
max: current.max,

New blog post: Rules, Types, and Glue: A Multi-Paradigm Architecture for Game Simulation 🎮🧱

A deep dive into combining classical AI and strict type systems for high-performance simulation engines. I evaluate:
🧠 Prolog for symbolic reasoning (Rules)
🧱 Coalton for static type-safety (Types)
🔄 Common Lisp as the high-speed runtime (Glue)

Includes SBCL vs. ECL performance benchmarks.

There's an "Ultimate Functional Programming Bundle" on Humble Bundle right now. And…

… if only I had more time (and a need (and fewer constraints on colleagues _also_ needing to know it))…

The "Seven Obscure Languages in Seven Weeks" book particularly caught my eye 😁
