      I've seen Go folks say, in effect, "Rust's experience with try doesn't apply to Go because Rust users don't have as strong opinions on readability as we do." Oh, you sweet summer child...

      For whatever reason it seems a fairly pervasive opinion that an additional 3 lines of error handling boilerplate per function call is more readable somehow: https://old.reddit.com/r/golang/comments/c9qj8j/one_of_rusts_designers_on_going_from_explicit/et3bzu7/ …

      try would be over-applied by new and intermediate Gophers, and yes, I think it would make those codebases significantly more difficult to read and maintain

      try makes code less readable because it’s (a) nestable and (b) triggers a function exit. other proposals that also reduce SLoC but don’t have these properties (i.e. are keywords) are much better

      No, that has not been our experience at all. Try is more than clear and readable enough. I confess I have trouble understanding why the experience of Rust is so casually dismissed in these conversations.

      It's like... we literally did an experiment to answer the question "does try reduce readability"? The results were clear.

      Mine is a loaded opinion (I agree with Peter), but I think drawing comparisons between Go and Rust's readability may not be effective. People who've used Go substantially are likely to think its readability is one of its best features, and it will be defended as such.

      You’re effectively saying that Rust users don’t care about readability as much as Go users. That is completely false, as reading almost any RFC will make clear.

          I’m saying that readability means different things in different co texts (languages). I would further argue that Go readability is much higher than Rust readability, and in no small part to things like the lack of the try/? macro.

          Now you’re trying to argue that Rust would be more readable without having try or ?. No.
