It's historically like that in Haskell, and that's how the library defines it. I agree that Result is much clearer, and would love to use it here. But then I would also have to go through how to use Algae to define the type instead of using it out of the box, which would make the article longer. Similarly with typechecking -- Elixir is dynamically typed, not everyone uses dialyxir, and to bring that whole story inside would also complicate the article. I plan to continue exploring this space, and perhaps I will slowly understand how to best introduce these ideas to Elixir people correctly, but right now I am just trying to approach it from different kinds of angles. Thank you for the comments. :) -- Author
