Fear the Obj.magic

Let me first quote a paragraph from the Memory Representation of Values (with my emphasis):

Obj is an undocumented module that exposes the internals of the OCaml compiler and runtime. It is very useful for

Solving SAT via interaction net superpositions

I've recently been amazed, if not mind-blown, by how a very simple, "one-line" SAT solver on Interaction Nets can outperform brute-force by orders of magnitude by exploiting "superposed booleans" and optimal evaluation of λ-expressions. In this brief note, I'll provide some background for you to understand how this works, and then I'll present a simple code you can run in your own computer to observe and replicate this effect. Note this is a new observation, so I know little about how this algorithm behaves asymptotically, but I find it quite

# 1. Clone/download/copy-paste the this script
# 2. Give it rights to execute: `chmod +x d.sh`
# 3. Move it somewhere on your PATH and (optionally) rename it on the fly: `mv d.sh /usr/local/bin/d`

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

1. Use ESM yourself. (preferred)
   Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
3. Stay on the existing version of the package until you can move to ESM.
