Walter Bright (D's author) said something like: who's going to check the error returned by the log functions?
I would add if you want to be correct then the addition signature should be (IntX, IntX) -> Either<IntX,Error>.
Are you going to check also the return value of every arithmetic operation?
For me potentials errors are everywhere, so exception aren't bad, even if they make writing 'exception safe' code hard. That's why I was quite interested in the Vale language which claims to improve RAII: https://vale.dev/blog/next-steps-raii
