Rust and D and probably others have this too. The interesting question is:

Can you chain these operations in a way that will propagate the error to the end result while simultaneously have a compiler produce code without branches after every operation. Safe integer operations alone are not enough for that.

I think the operators panic. In zig, If you want safe operations I think there are functions in the stdlib

The branching does not cost as much as you think, I'm pretty sure the compiler marks the erroring path as cold, which the cpu can use to elide most of the branch cost through specex

A branch is a branch and no branch will always be better. With sticky flags there is no difference in performance to regular integer arithmetic.
