A simple Java question, what this code does ?
ArrayList<String> list = new ArrayList<>();
list.add("foo");
list.add("bar");
for(String s: list) {

We could improve the best-effort basis by which ConcurrentModificationException
is thrown by snapshotting the collection size on construction of the iterator
(at the expense of an extra field, but that might pack into a spare 4 bytes due
to alignment at least on 64 bits IIUC).
Or call checkForComodification() when cursor == size in hasNext()?

tip: the bug lies in ArrayList.Itr.hasNext() (and AbstractList.Itr.hasNext()).
