That’s only true in crappy languages that have no concept of async workflows, monads, effects systems, etc.
Sad to see that an intentionally weak/limited language like Go is now the counterargument for good modeling of errors.
I naively thought it I may as well take a job using Go, as learning a new language is broadening, and some people like it, so lets find out first hand... I knew it was a questionable choice, looking at how Go adoption tailed off a while ago.
Turns out I hate Go. Sure it's better than C but that's a very low bar, and C was never a good alternative choice for the use cases I'm encountering. I'm probably suffering from a codebase of bad Go, but holy shit it's painful. So much silent propagation of errors up the stack so you never know where the origin of the error was. So very much boilerplate to expand simple activities into long unreadable functions. Various Go problems I've hit can be ameliorated if you "don't do it like that", but in the real world people "do it like that" all the time.
I'm really starting to feel like there are a lot of people in the company I've joined who like to keep their world obtuse and convoluted for job security.
Can you please demonstrate how async workflows and monads resolve this issue?
Wouldn't effect systems still be considered exceptions, but handled differently?
I don't know the answer to your question, but I think that what is needed is just a bit of syntactic sugar, e.g. Rust has
?for returning compatible errors without looking into them. That seems to be powered byTrytrait, that may be a monad, but I am not fluent enough to check if it formally is.
