I was thinking about the case where there is a `?` in the code but the reader glossed over it, thinking it didn't return an error.

There is no way to discard the error without explicitly doing so, and even then you still have to decide on a non-error return value to return (because Rust functions that fail provide an error or a value and not both, unlike fallible golang functions). I agree, I think Rust is strictly better in this capacity.

> People who believe Golang is explicit and hard to ignore errors but think that Rust is implicit and easy to ignore errors have never used both languages, full stop. I challenge you to provide me with an example of Rust code that ignores an error without explicitly and obviously doing so.

You seem to be unduly defensive. This was never my claim. I have used and enjoy Rust. We're all friends here :)

The error is explicitly in the function prototype. Every code path that returns must ensure the result is an `Ok(T)` or an `Err(E)`. You just can't accidentally overlook this. Even if you do gloss over it when skimming, the error is handled and dealt with.

I'm just tired of hearing that Golang's error syntax is explicit but Rust's is somehow implicit because it's fewer characters, even if they desugar to virtually exactly the same thing. Both are explicit. Golang's is verbose and (ironically) error-prone.

Some of us are mere mortals. We tire and make mistakes. Perhaps even unworthy of the mantle of "Rust programmer".

I already admitted sympathy to the viewpoint that Rust's error handling is technically explicit, and that Go's error handling would be improved by static verification that errors are handled. What more do you want from me?
