A slice is a value but a map is implemented as a pointer. IOW, the line of code quoted above updates only the locally visible copy of m. All other copies of m are left at the old, possibly nil, value, but that's not how maps in Go work. Once the map is initialized, all the shared copies can access the same values/operations on it. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
