> Bugs like this aren’t possible at all in Go or C# As a point of order, such bugs are possible for Go. Eg, hashmap's behaviour becomes undefined if you access from multiple threads at the same time. Admittedly, that's a Go peculiarity. Making the programmer deal with concurrency on collections undoubtedly gets it a speed boost, but it's not the tradeoff most gc languages take. The beauty of Rust, is you don't need to trade speed or memory for concurrency.
