Indeed, it's invaluable. I use "go vet" and have enabled all of the Gometalinter linters [1] that make sense. "go vet" never warned me about goroutine closure errors, not sure why, maybe I was running an old version. But I'm glad that it's supported. That said, some of the things that "go vet" catches should, in my opinion, be errors. [1] https://github.com/alecthomas/gometalinter https://github.com/alecthomas/gometalinter
