Same goes for a lot of things. Want to know how Windows ticks? Try
reimplementing it - or read the comments left behind by people who've
done that, by browsing the Wine sources. There have been times when
I've been trying to figure out how to use a particular Windows API
function or window message, and couldn't understand some edge case
based solely on the docs, so I dug into the Wine source code, found
how they did it (and in at least one case, found a comment stating
that observed behaviour differed from the docs!), and was able to
deploy to Windows on that basis.

I'm sure implementing Python is a lot more fun than reimplementing Windows APIs!
