I see nothing wrong with how Go&#x27;s map implementation was described. Go has never claimed to be completely safe for concurrent operations. Deadlocks, inconsistent state, etc are more than easy to accomplish. But, it still stands up to a &quot;good for concurrency&quot; claim by offering nice primitives for writing concurrent code, a race detector and explicitly stating in the stdlib documentation which libraries are thread-safe -- libraries are to be considered not safe unless explicitly said to be.
