I think my proposal has the least broken

Duplicate of #14066

@seankhliao I don't know why you just because of they looks similar then close this, this has diffrence, this issue add limit for sugar so it easy to implement

We have rejected many issues that are very similar, if not identical, to this one. Just as those were not accepted, we aren't going to accept this one. As I mentioned, please see #40432. Sorry.

so much proposal, can we make an vote to known which proposal is much popular?
I really hate go error handle, so much template code

Sorry, we don't make changes to the Go language on the basis of voting.

We are aware that error handling boilerplate is a concern. There have been many, many, proposals to address it. There has been an enormous amount of discussion on the topic.

here is my try: https://github.com/shynome/err4 .implement this by use code generate.

I'm so sorry for what I said. I didn't mean to hurt your feelings.

No worries.

#14066 (comment)

I think the Proposal-Decline reason does not apply now, This year is 2023 not 2016, this year we have got generic type, a change bigger than this proposal, golang team can consider this again

We've identified many similar issues. They have all been closed. This isn't an approach we are likely to take with Go. Sorry.
