Thanks for the comments. The Author here. I know the article does indeed lack depth. But on the other hand, I have a precise goal in all the articles I write for this newsletter. I just want to introduce some concepts, which are not commonplace, very briefly. so that you can read in an email, in 2-3 minutes max. I try most of the time to point out to the original documentation so that anyone curious to know more can follow and learn the details.

What do you think about this approach?

(That is kind of why I named the newsletter as `Python's Byte` :) )
