It is a library that defines a type.
It is not a new type system, or an extension to any particularly complicated type system.

Bayes isn't mentioned in the linked article. But thanks for the links.
That did not surprise me because I did not think the article was about anything but about adapting the dot-net library they linked to on Microsoft's site to swift, and I figured that if I wanted to understand the library and the approach I had better read the links that indicated I might be able to learn from them.
