Keep one thing in mind: if you want the element remains legal after the function call ends (maybe map(), flatmap(), depends on what you are using), you should copy the elements. Typical scenarios includes: 1. Save the elements into some collection like array, list, map for later usage, you should copy it explicitly. 2. Pass the element into some async calls, you should copy it.
