>IIRC, the author's name was Jonathan Amsterdam. Googled his name and found this video by a person with that name, may be the same person whom I mentioned above.

GopherCon 2017 - Lightning Talk: Jonathan Amsterdam - Errors as Side Notes https://www.youtube.com/watch?v=_wW2U9SGKKI https://www.youtube.com/watch?v=_wW2U9SGKKI Update: I just watched the video, it's very short, and the tool he describes seems useful for understanding new Go code. I won't describe what it does - go watch the video (pun intended).
