FWIW I thought the article was fine, when though I love go. I do think it reads like you wish you could use Rust or something. It is nice to hear about hassles from someone who has actually used the language for a change. Not every language is for everyone, that's OK. Obviously, most people who love the Haskell style of type classes and pattern matching are going to find much packing in go. That's OK.
I could and probably will blog about problems with the Haskell as well - nothing is perfect.
