Ow My Foot – Error Handling Across C, Go, Rust, and Google's Absl

Author here. I've been working with Rust more recently, and thinking through its error handling ecosystem led me down a rabbit hole comparing it to what I'd used before — C, Go, exceptions, and Google's Absl Status. The post ended up being a broader survey of error handling principles across languages and organizations than I originally planned. Looking forward to input — I'd love to hear what your experiences with error handling have been like, especially across different languages or at scale.

Great survey. One thing I'd push further on your principle 2.3: the reason .context() chains work better than stack traces isn't just ergonomics, it's that they preserve causal information rather than mechanical information. A stack trace tells you which functions were on the call stack. A context chain tells you what the program was trying to do. These are fundamentally different things, and the gap widens dramatically with async code, where the mechanical stack is often meaningless.

Interesting. The Odin Programming Language has some primitives that are pretty similar to Absail's macros.

For control-flow we've got the postfix operators: `or_return`, `or_break`, `or_continue` For alternative values we've got postfix `or_else`.

Considering how much I enjoy Odin I should probably entertain using Absail for my next C++ project.
