Very good article, thank you.

I would add that the tagline says "when used thoughtlessly".

For example, I agree that using Result objects to reinvent exceptions is a bad idea. There's a reason they're called "exceptions". Error results should only be used for domain-level errors. ie. things that _your expect_ to go wrong in the domain.

Also note that in my article I use continue/halt, not Ok/Error. At the library level it's just a way to compose functions together with a mechanism to halt processing. Whether something halted execution because it was an error, or any other reason (ex. caching), is up to your app's semantics.
