That's fair enough; it's a language you're more confident with. I've spent two years doing Go regularly now, and at the moment I can whip up valid Go code without tooling or running it in between, but it took me a good amount of time and practice.

I also believe these are the biggest challenges in the Go ecosystem at the moment, and it's probably the most frequently asked question in the various communities. Code / codebase layout is still a very opinionated thing, and while there's a handful of good ideas, there's no standard. (on that note, ignore the "golang-standards" github account, those are NOT standards).
