I avoid using exceptions myself so I wouldn't be surprised if I misunderstand them :) I love to learn and welcome new knowledge and/or correction of misunderstandings if you have them.

I'll add that inspiration for the article came about because It was striking to me how Bjarne's example which was suppose to show a better way to manage resources introduced so many issues. The blog post goes over those issues and talks about possible solutions, all of which aren't great. I think however these problems with exceptions don't manifest into bigger issues because programmers just kinda learn to avoid exceptions. So, the post was trying to go into why we avoid them.

RAISI is always wrong because the whole advantage of the try block is to write a unit of code as if it can't fail so that what said unit is intended to do if no errors occur is very local.

If you really want to handle an error coming from a single operation, you can create a new function, or immediately invoke a lambda. This would remove the need break RAII and making your class more brittle to use.

You can be exhaustive with try/catch if you're willing to lose some information, whether that's catching a base exception, or use the catch all block.

If you know what all the base classes your program throws, you can centralize your catch all and recover some information using a Lippincott function.

I've done my own exploring in the past with the thought experiment of, what would a codebase which only uses exceptions for error handling look like, and can you reason with it? And I concluded you can, there's just a different mentality of how you look at your code.

No offense, but why did you decide to write an instructional article about a topic that you "wouldn't be surprised that you misunderstand"? Why are you trying to teach to others what you admittedly don't have a very solid handle on?

None taken :) I think sharing our thoughts and discussing them is how we learn and grow. The best people in their craft are those who aren't afraid to put themselves out there, even if they're wrong, how else would you find out?
