This is rather sad that one must give up the range and add the signed range just to avoid overflow bugs. Is there no way to make overflow not the default and instead trap unless one uses `add_wrap()` or `add_no_wrap()` in case it's not default?

There is overflow-checking math in GCC/Clang and standardized in C23, but I'm not sure if there's anything opt-out. If there is, I don't know how to write it.
