Sorry, if I'm coming across like I'm lecturing you. I'm not trying to. I'm
trying to be clear about the situation, and because this is on D.Learn, with
something like this, I don't want to show how to get around the issue
without clearly warning about the risks, because even if you know exactly
what you're doing when casting to get around purity problems, many others
reading this list will not.
