The real answer is I don't know. I just know like 2 people who understand the paper I linked (one of them being the author and I don't mean that I've met or talked to them just that they are a person that I am aware has understanding of the paper) and every other developer I've seen kinda struggles to fully comprehend what's going on with it.
Now, this is what specs are for, so maybe we'll get a spec of John Law's favorite paper one day.
