You can't decide to avoid the boilerplate though at the moment, because there is no try. You can only type out the boilerplate, and read it, even if you don't really need it in that particular instance. It would not reduce code quality if used in instances where it replaces return nil, err - which is what it is intended for. It's not intended to replace wrapped errors, or error handling, it's intended to replace 3 lines of boilerplate with one word - in the cases where you want to push the error one level up the call stack. Having used go extensively for the last 5 years and built some large projects with it, I disagree this is not useful. I think it's a good proposal in the spirit of go and should be adopted. I'd prefer this as a keyword myself, but of the 6 million instances of if err != nil on github, I think around half could be eliminated by this pattern, so I think it would be useful, if not overused. https://github.com/search?l=Go&q=if+err+%21%3D+nil+%7B&type=... |
