I have to look at the files one by one because for instance here, the constructor was not affected by Rector.

I think it will be better to touch the walkers after #9551 is finished. I will remove change to them from this PR |

It was already an ArrayIterator before, but should this method rely on an Iterator implementation in the return type instead of the interface itself? Even the name of the method doesn't refer to a specific Iterator implementation.
It's not really a blocker for a merge, but food for thoughts for 3.0.

No, no, I totally see what you mean: if the consumer don't leverage it, why should we provide that level of detail. Here, they shouldn't be calling getIterator() directly but use a foreach, so that's one more reason to do this. Let me change that.

Yes, IteratorAggregate allows to access getIterator() directly. Technically it should be Traversable as the docs suggests, but I wasn't sure if this step was a too large for this PR.
That way we have some level of error handling, and don't muddy the return type.
