Rust's error handling evolution is hilarious. In the beginning, the language designers threw out exceptions --- mostly, I think, because Go was fashionable at the time. Then, slowly, Rust evolved various forms of syntactic sugar that transformed its explicit error returns into something reminiscent of exceptions.

Once every return is a Result, every call a ?, and every error a yeet, what's the difference between your program and one with exceptions except the Result program being syntactically noisy and full of footguns?

Better for a language to be exceptional from the start. Most code can fail, so fallibility should be the default. The proper response to failure is usually propagating it up the stack, so that should be the default too.

What do you get? Exceptions.
