You're right. Sorry.

My actual reply to Matt was actually just this paragraph,

and what followed was an attempt to show that the simple exercise in
writing quines wasn't just hand-waving. I should've deleted it after
seeing how long it got... I'll try to learn the lesson for next time.

What I find unfortunate is people throwing their intuitions at each
other without ever trying to address objections on their own grounds,
but since I haven't managed to do better, I must accept the rebuke :-)

All the best,
