Uncertain<T>

[flagged]

I don't think inference is part of this at all, frequentist or otherwise.

It's not part of the type system, it's just the giry monad as a library.

As presented in the article, it is indeed just a library.

Bayes is mentioned on page 46.

It is a library that defines a type.

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

It was chosen to be implemented as a generic type in this design because the way that uncertainty "pollutes" underlying values maps well onto monads which were expressed through generics in this case.

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.
