Yeah no, that is not what I meant. It is possible to make error-handling even more ergonomic while staying fully explicit. I agree that implicit/magical/runtime error-handling is not more ergonomic.

I briefly looked at those crates, but while they make some parts better, they make others (for instance the explicitness) worse. On top of that, they are built using macros, which is totally okay from the perspective of the library and comes at a cost.
Overall it would simply be better if Rust's typesystem were capable enough so that those macros were not even needed.
All of that being said, Rust's error-handling is still good. I'm just bothered by the "Rust nailed it perfectly" attitude. It's better to be aware that there are even better solutions out there, so that we can go and improve Rust even more.
