I don't think it's immediately obvious what use cases this "int?" proposal delivers that aren't covered by "*int". The encoding/json package uses pointers to support null JSON values.

I think it's reasonable for the burden of proof to be put upon the asker, who is looking to others for help. On Sat, Aug 19, 2017 at 9:28 PM Tong Sun <suntong...@gmail.com> wrote: > Oh yeah?
