Ever since I started writing Go professionally I've gotten into the habit of annotating errors in other languages as well. The difference between Go and Haskell is then mostly one of a few characters and some syntax differences. But conceptually it's exactly the same. Take the error returned by some function call, add a bit more context so I can differentiate this XYZ error from the others, then pass it along to the caller. I really couldn't care less about the details of how that happens and I find it puzzling that someone would write such a lengthy blog post about what is to me a completely trivial matter.
