I find that Go errs way too strongly on the explicit side, but overall it's still better than many other alternatives. For error handling I tend to write in a style where errors are either asserted out or "folded". If I do several operations in sequence any of them could err, I code in a way where I don't check every single op: instead I make some kind of "error accumulator", or write the code in a style such that if the previous operation failed the next operation will become effectively noop. I then check for errors at the end of the process. That said, Go is actually right about treating errors as values and not giving special language constructs to throw/catch them. |

Errors are still values in Rust - usually as part of the `Result` type - but unlike Go, it actually has tools to let you deal with them in a convenient way, like the `?` propagation operator (https://doc.rust-lang.org/book/ch09-02-recoverable-errors-wi...), or the functions on the `Result` type like `map`, `and_then`, `map_err`, or crates like `thiserror` for defining error types, and `anyhow` for easily converting them when you don't care about the details.
