Context: I've been programming in Go full-time for the last 2 years and come from a Python and C# background.

  > No Generics

The lack of generics was something I was hung up on, too, but TBH I haven't found myself reaching for them for a while now.

  > Error handling

This is not a problem for me, either. I can easily handle different `error` types and if I want to provide more context I pull in github.com/pkg/errors

  > gofmt

gofmt is great

  > go test

go test has been totally sufficient for me and I was quickly writing and running tests. The testing package itself is builtin and writing tests is dead simple.

  > dep / dependency stability

Dependency management has been a huge PITA with Go and is my largest complaint. Personally, I've used everything go GB vendor, godeps, glide, and now dep. dep has been Just Working for me and is decent enough working on a team. As for dumping the dependency code in your source tree-- it lives in a folder called ./vendor so it's easy enough to not look at it.
