I believe it is. We can always change things in response to new information - we could, theoretically, even change decisions we made years ago. However, it should be clear that the bar for what constitutes a "good reason" becomes higher over time. In particular, after the acceptance of the proposal, the minimum bar is that it really is new information. Because if the argument was already known, it was already considered and weighed as part of the decision. As far as I can tell, the things mentioned in this thread (and other recent threads on this list) are not new. New information might be some technical difficulty in the implementation, or a corner case or fundamental problem we didn't know before. Evidence for overwhelming resistance to generics could also be new information. Though I'm not sure where it's supposed to come from - as mentioned a couple of times, it's hard to get representative polling information. But this was what ultimately killed the `try` error handling proposal, so it's not unthinkable. > > Thanks for your patience > > > > > Ian > > > > > > > >> ср, 17 мар. 2021 г. в 02:12, Ian Lance Taylor <i...@golang.org>: > >>> > >>> On Tue, Mar 16, 2021 at 6:51 AM Space A. <reexist...@gmail.com> wrote: > >>> > > >>> > > (To be clear, your original claim was that there *was* no > discussion - which is at least easy to address, because it's clearly not > true.
