Of all the absolutely fantastic stuff that Zig gets right, I think my favourite is the error handling.

While it would be cool to get an error payload, I would hope that if that was added to the language, that it doesn't affect the current ergonomics of error handling.

Where I've really needed to get some data back out, I've passed in a pointer to a struct that gets populated.

it has the same issues. You can always discard errors with `catch unreachable` for example.

If you haven't overridden the default panic handler, and you're in a Debug or ReleaseSafe build you'll still automatically get an error return trace (which is nicer than a stack trace) even if you do `catch unreachable`.

True, but it's very explicit, and easy to audit for.
