I was excited to see that not only does this article cover other languages, but that this error happens in go. I was a bit surprised because map access is generally protected by a race detector, but the RedBlack tree used doesn't store anything in a map anywhere.

I wonder if the full race detector, go run -race, would catch it or not. I also want to explore if the RB tree used a slice instead of two different struct members if that would trigger the runtime race detector. So many things to try when I get back to a computer with go on it.
