Hmm. I guess I understand what it's doing now. Just feels like a
strange way to do it. Might be simpler to leave this part to the
caller. But then we're perhaps going to have to update several callers
which isn't so great either. Not sure. At least it needs a comment
of some sort to explain wtf is going on.
