While we could keep playing language-of-the-week-golf -- the go compiler is born from the plan9 c-compiler, and the go designer(s) had a hand in designing plan9. So my comment wasn't quite meant as just a popular-language-x-quip. Plan9 reborn in gopher clothing actually has some merit.
(Not that plan9 in rust wouldn't have merit -- I wonder, post Rust 1.0, if someone ends up writing a full OS, starting with Rust and as much assembler as needed -- if it would make sense to mix go and rust for some of the user-space -- or if it'd make more sense to just stick with Rust).
