> Unlike many of the complaints about Go that would require fundamental restructuring, C# showed that actually can be retrofitted onto a language without breaking it. C# added nullable types. Not non-nullable types. In Go, the concept of zero values is so fundamentally baked into the semantics that non-nil pointers can never really be added to it.
