Checked exceptions suck. Every method has to explicitly throw them up to a higher level where they can be handled causing tons of useless boilerplate. Its much better to just let unchecked exception bubble to a higher level of the app. This is a best practice in java so letting the exception bubble all the way back to the user is just poor programming.
- erikb 9y agoI have to google what the "checked" actually means. But in Java you can throw parent classes, in Python you don't need to declare them at all. And honestly having a bad implementation is still better than no implementation. The main point here is to get correct, helpful error reporting so people understand what's going on. If I spend another 4 hours debugging an error message that was actually just a warning and not a biggy at all I'm going to throw up.
- alphaalpha101 9y agoThat's exactly what you have to do in Rust anyway though. Except instead of just writing `throws SomeError` in the declaration line of the function, you have to annotate virtually every line of your function with `?` and wrap the return line in `Ok(...)`.
- steveklabnik 9y agoThe ? RFC did include a "catch" construct, and there's been some discussion about doing something more like "throws SomeError." We'll see!
