eh, I disagree. It's not massive overhead, but it turns literally every integer operation into a branch. Sure the branch is going to get ~100% prediction accura

eh, I disagree. It's not massive overhead, but it turns literally every integer operation into a branch. Sure the branch is going to get ~100% prediction accuracy if you aren't using bigints, but that's still a pretty big cost especially since the branches inserted make all sorts of compiler optimizations illegal.
