Can golang lock be copied?
Article Introduction:No, because locks are used to control access to shared resources. Copying a lock may lead to multiple unlocking operations on the same resource, causing resource competition and deadlock problems. In Golang, when assigning a reference type variable or passing parameters, it only copies the pointer itself, rather than copying the data pointed to by the pointer. This means that copying a variable of type Mutex only copies the pointer to the lock, not the lock itself.
