Get an arbitrary key/item from a map

Question

I am new to Go and now I want to get an arbitrary item from a map; what\'s the idiomatic way to do that? I can only think of something like this:

func get_some_k

Here is a more generic version, although it may be less efficient:

    keys := reflect.ValueOf(mapI).MapKeys()
    return keys[rand.Intn(len(keys))].Interface()
