IMO exceptions are a terrible way to signal errors. They obscure control flow and make it much harder to reason about a program's behavior. They make it easy to forget to check for errors, and encourage sloppy catch-all error handling. It is a lot harder to determine if exception-based code is correct or not, and languages that have exceptions require you to examine literally every line of code to determine if it can throw.

Even the name is wrong: an "exception" should signal truly exceptional behavior, things that you would not expect to happen unless something is really wrong. And yet exceptions are thrown for mundane things like "file not found", something you could very easily expect to happen routinely.

Exceptions should be like Rust's `panic!()`: only for things that the programmer can't reasonably do anything about, which will cause the program to terminate.
