I'm giving a Pony workshop at ICFP this year (https://icfp18.sigplan.org/event/icfp-2018-tutorials-writing...), this repo represents the material that I'll be covering. I've given early versions of it twice in NYC. I think it kind of works as a stand-alone thing (but you miss the thrill of hearing my voice and asking questions).
I'd love to get some feedback if anybody has any thoughts.
