We will rewrite pretty much every single line of this function
over the course of the next several commits, and starting from
a clean slate rather than replacing it bit by bit makes the
resulting diffs unmeasurably easier to read and understand,
and you need fewer of them to boot. Trust me, I tried the other
approach first :)
