Heh, it's not like all this is something that comes up every day - the
compiler and eval loop mostly sit in the corner chugging away quietly
without bothering anyone. The main advantage of experience is knowing
what all the moving parts are and where in the code base to look to
refresh my recollection of any details I've forgotten :)

The only comment I'd make about your explanation is that a lot of
those details aren't actually part of the language spec - they're
implementation details of CPython that other implementations may
happen to follow because it's a reasonable way to do things. They can
still be a useful intuition pump in helping to figure out what is and
isn't feasible in the language design, though.

Cheers,
Nick.
