list before any iterator is taken = [Apple, Banana, Cherry]

beforeWrite.next() = Apple
|

[writer] added Date and Elderberry - list is now [Apple, Banana, Cherry, Date, Elderberry]
|
|
|
|
=== beforeWrite iterator was created BEFORE the write - draining the rest of it ===
|
|
beforeWrite.next() = Banana
|
|
beforeWrite.next() = Cherry
|
|
beforeWrite never saw Date or Elderberry, and threw no exception.

=== afterWrite iterator is created AFTER the write - it sees the current array ===

afterWrite.next() = Apple

afterWrite.next() = Cherry

|
afterWrite.next() = Date

Final list = [Apple, Banana, Cherry, Date, Elderberry]
