> IME this is a longstanding pain point with Go.

Understatement of the year. But it’s really not limited to encoding but generally lack of sum types is excruciating after having tasted them (in Rust, in my case). They click instantly as an abstraction and they solve countless real-world logic bugs. Not to mention their ergonomics in seemingly unrelated things like eliminating null and error handling with result types. Just sprinkle some pattern matching on top and you’re in paradise.
