All it takes is a specially formatted comment

    /*
    int g() {
     volatile int x;
     return x;
    }
    */
    import "C"

    import "fmt"

    func main() {
     fmt.Printf("%d\n", C.g())
    }

But I know you'll say that 'import "C"' or 'import "unsafe"' is the same thing as using an unsafe block in rust or such, and really shouldn't count against go.

Which is fair and true, but you're chasing down a pointless detail. The point isn't that go is memory unsafe. It's not. The point is that Go's type-system is not powerful enough to express various types of type-safety, and as such it's an error-prone language where you can expect null pointer exceptions frequently.
