I'm not going to talk about errorOr specifically because I don't know how it's implemented but rather your premise.

Exceptions are the modern goto, the try catch may be in the caller function. Or it could be 3 inherented classes away (this is hyperbole, I'm not sure if it would actually work) with so much indirection it would be impossible to follow the code flow other than to step in a debugger. So in fact it's worse than a goto since at least a goto had a label.

I'm not for or against exceptions just pointing out that a result or optional type is in no way at all similar to an exception.

On another point C++ exceptions are notoriously inefficient as well. There ware valid reasons to want to be exception free even from a code style perspective.

I'd argue that pubsub systems are the modern goto, but exceptions certainly come in a not too distant second.

When you wrote pubsub, did you mean “the observer design pattern”? If so, please try to adopt a more formal lexicon and use terminology familiar to more developers. If not, please describe what a “pubsub” is.

[snovv_crash]

No, I don't mean the observer pattern. I mean publisher subscriber pattern.

Observer pattern is fine, because there is still a link between the execution flow; basically any time you register a callback you're using the observer pattern.

Pubsub adds a middleware, typically in the form of a message passing framework, so that both publisher and subscriber aren't necessarily aware of each others existence. The publisher throws its data into the framework hoping someone finds it useful, and the subscriber listens for those messages hoping someone is publishing them. Think of it like multithread asynchronous goto of your execution flow, except with a lot more boilerplate.

Wait I need to hear more about this.

How are pubsub systems a modern goto? Genuinely curious since I don't work with them directly that often

[snovv_crash]

If you give me a high level explanation about why goto is bad I can basically /s/goto/pubsub and it will still hold mostly true.
