Those are not exceptions by most reasonable definitions. Exceptions are a general purpose error handling method. Try, catch and all that. They are almost always objects with multiple types.

Go and Rust's panic is for unrecoverable errors. They both have the ability to catch panics because sometimes you really need to do that (e.g. when interacting with FFI or sometimes multithreaded code).

They are not exceptions though. I've seen this myth repeated a few times lately (always about Go and not Rust for some reason) and I wish it would die.

You wouldn't say C "has exceptions" would you?
