I ran `mvn clean install` and everything passed. I reviewed the code and
these are very simple changes to our `TraversalHelper`/`DefaultTraversal`
classes. For example, replacing `Stream` with `for-loop` is always good. Given
that these methods are so core to everything traversal, making these as fast as
possible is smart. Thus, this is a really useful PR. Hopefully we can expose
more performance problem areas and address them much like this ticket.
