Calling exceptions "Go envy" or a "mistake" seems like naive criticism. Ignoring the fact that the Rust is as old as Go; there is a lot of time spent in building language features with an, from my point of view, academic level of rigor.

There have been a lot of RFCs discussing exceptions in Rust[1][2][3], and the tradeoffs and design have been discussed thoroughly. If you have a design in mind that is safe, robust and performant you are welcome to submit one - as my understanding is the Rust team does not have an ideological slant against exceptions.

I've never understood the hard-on by some C++ fanboys to rush exceptions. You can build (IMO) more reasonable code without abusing ~~gotos~~ exceptions, and a bad exception design (like Java's) is strictly worse than even Go's error handling.

Besides, Result types with sufficiently advanced ergonomics might as well be semantically identical to exceptions.

The so called "Java design" as urban myth, traces back to CLU, Mesa/Cedar, Modula-2+, Modula-3, and C++.

Naturally the Java designers thought to adopt a feature that was increasingly being made available.

And they only got out of C++ due to the language dialects out there regarding RTTI and exceptions.
