Well, sort of, yes. https://play.golang.org/p/qyfqZA5pww https://play.golang.org/p/qyfqZA5pww func main() { go fmt.Println("Hi!") } This is a valid go program (eliding import etc), and it'll almost never print anything. This is actually a classic mistake when starting with goroutines - not adding synchronization to make sure your main goroutine doesn't exit before any spawned goroutines.
