While I have been a member of the "unsigned counting variable" minority for a long time, this kinda drives the nails into the coffin for a lot of signed array index / offset use. It's just too big a risk to accidentally have the compiler go YOLO on you for some minor detail you missed.

Also, this UB optimization train has gone way too far and needs to back up a few stations.

I'm gonna say there needs to be a switch to make signed overflow not be UB. Maybe that already exists? starts checking docs
