I understand the the issue you are having. We had the same where we differentiate between absent string and empty string. It was messy with data from json but it worked.
I think "int?", Optional or Maybe are not as helpful in Go as they can be in Java or perhaps C# since a small type with custom marshalling can make this safe when needed. That said, some standard way of denoting "absent" in cases with json or protobuf (??) or xml would be nice. How is this case catered to in for example gRPC? mån 21 aug. 2017 kl 15:24 skrev Tong Sun <suntong...@gmail.com>: > > > On Monday, August 21, 2017 at 3:44:41 AM UTC-4, Henry wrote: > > In my opinion, if you need a nullable type, you're entering a domain >> problem.
