Hi, author here. I agree that straight away throwing a bunch of language extensions without an explanation of why we need them at all wasn't a good idea. The original blog post was written in literate Haskell, that's the reason why the code is organized that way.

I will think about rearranging the code blocks or add more explanations to make it all fit more naturally. Thanks for your feedback!

When I teach or write about Haskell I try to break down the parts in a way that the parts can be tested using ghci and just composing it at the end.

I think there are quite a few parts in there that one can easily "try out on their own".
