As a counterpoint, see this blog post on why wrapping-overflow-is-UB is bad for safety and correctness:
https://c3.handmade.network/blog/p/7640-on_arithmetics_and_o...The gist of it is that (a + b) - c becomes different from a + (b - c) and (a - c) + b.
While Rust picks a “fast” default that ensures non-trapping code is safe in this regard.
Zig on the other hand would make incorrect ordering UB which might not be immediately obviously wrong - it completely depends on the optimizations run, something which runs completely counter to notions of correctness.
