Other programmers tend to be bad at reliably cleaning up resources such as file handles, locks etc, so I need to inspect the whole invocation tree anyways to have an understanding of what runtime implications I've summoned by invoking other people's code.

As for myself, I've lived through the hell the are checked exceptions in Java. You learn that compositionality and checked exceptions are at odds when you try to insert a remoting layer into an application that has grown without IOExceptions. Then you learn that it's actually not necessary to know the set of possible errors, just make sure that you're not a bad programmer as in my first paragraph, and everyone will be fine. This is also something that you can learn from Exceptional C++.

Yeah, I’ve never understood the complaints about exceptions either: most of the time you want the exceptions to just bubble up anyway because, in that case, you only have to think about the contracts of the functions you interact with and not about the unusual states you might be in. Return-type or return-value based error handling has always seemed to me to be significantly worse.
