I think it was sarcasm. I have about as much experience as them in low-level C programming, and I was wondering why this is on front page. I've also discovered again a few things too, so I won't look down on OP. It's certainly better than vibe coding.

No, I'm being serious.

I know about XOR-linked lists and a few other tricks for very efficient memory usage in embedded systems, but it's my first time seeing implicit allocation lengths.
