Indeed. There is a legitimate use case of having both fast random
access on an arbitrary object (in my case a Page object) and insertion
ordered processing when iterating. Speed is an issue for me, but I
think people are trying to prematurely optimize. Where PDF::Writer is
slow, it is not because of an ordered hash.
