The problem arises when someone wants to append another item to the
list. Without the comma he has to change two lines which may cause
merge conflicts if two people add different items to the same struct.
That's why we usually have (unnecessary) commas on the last element of
a struct initializer (except when they are meant to be the last
element of course).
