Well, that's why I said I needed more time. :) I'm not expecting it to
be a breeze to read through dmd code. I've actually looked into it
briefly before when tracking down a compiler bug, but I've to say that
in order to understand the code you need to first understand how it
works at a high level (yes, it's sorta a chicken-and-egg problem),
otherwise you're just looking at the trees and not seeing the forest.
