Exceptions are often a better way to handle errors than returning them as values. We argue that traditional exceptions provide better user and developer experience, and show that they even result in faster execution.

    Does the performance cost of error checking/result types they discovered in C++ apply to languages that have native result and option types like Rust?

    I would hope they were able to find efficient, performant implementations, and that branch prediction picks the expected non-error branch in most cases.
