Review Comment:
Didn't spend too much time looking at it, as weird things were happening
with breakpoints that I didn't understand when I was trying to run it locally,
but now I'm looking at it, it's pretty similar. Will take another look to see
if there's any bits of the original implementation I can add in here.
