alt Hacker NewsNo one here mentioned Zig approach there, so I'll share: https://ziglang.org/documentation/master/#try
Zig has try syntax that expands to `expr catch |e| return e`, neatly solving a common use case of returning an error to the caller.

Zig 'error types' are a sum type, while Go ones are just values.
And even then this is just the same as the '?' operator Rust uses, which is mentioned in the post.
The "Error Return Trace" described in the next section down also seems like an interesting alternative to a stack trace, possibly solving the same problem with less noise.
How well does it work in practice?
