I've tried to write up this topic in a clear, step-by-step manner,
with the help of diagrams and short examples from several different
OOP languages. I hope it will help clear up the confusion that seems
to be pervading the Python community (and which is far more rare in
the other language communities, despite them having the very same
semantics).

It's still a bit rough around the edges, and probably contains some
typos, as I finished it late last night and haven't even had a chance
to proof-read it yet. But I may not get another chance to work on it
for a few days, so I wanted to get it out there now. I welcome your
feedback.
Best,
- Joe
