Is this re-write for performance, or is there some other reason for it? I think
we should minimize the number of re-writes because they will cause problems when
we rename methods and fields.

nit: I don't like using "_" as an identifier. How about "operation"? (It takes
less of my mental energy to understand the code that way.)

It is much better to use idiomatic Dart implementation - it is easier and more
performant.
Our JavaInterator implementation is not so good.

Anyway, I will just remove the whole class.

     for (Iterator<IndexOperation> iter = operations.listIterator(); iter.hasNext();) {
       IndexOperation indexOperation = iter.next();
