> suppose you want Zig's "try" functionality with arbitrary payloads. Both functions need a compatible error type (a notable source of minor refactors bubbling into whole-project changes), or else you can accept a little more boilerplate and box everything with a library like `anyhow`. That's _fine_, but does it help you solve real problems? Opinions vary, but I think it mostly makes your life harder.

This is not true, you simply need to add a single new variant to the callers error type, and either a From impl or a manual conversion at the call site

"compatible error type"

Which is prone to causing propagating changes if you're not comfortable slapping duck tape on every conversion.

It depends on whether people depend on the structure of the errors. If they just stringify them, that shouldn't result in changes.

If people are getting into the structure of the errors, they might need to update their code that works with them.
