I wish Go had sum types too. But I like being able to write a mutable tree structure without first having to read a whole book on the subject and inventing a new system of pointers. Every language is tradeoffs.

Yes, the language does not have ADT support, but there are projects that enable this, like https://github.com/alecthomas/go-check-sumtype.
As a C++ dev, such comments reinforce my hesitation to pick up either Go or Rust seriously :) It seems I already have the golden middle after all.
If only C++ had a fully supported cargo system
I like the language saying "it's not as easy as you think" when I'm about to do something ill-advised like roll my own mutable tree structure.
It is in fact not that hard when your memory is automatically managed
You understand that tree structures aren't just lookup tables, right? I wouldn't roll my own red-black tree (Jesus how tedious would that be). That's not what I'm talking about.
I mean, it is as easy as you think in a GC language
Pointers are orthogonal to sum types. They are completely different things and there is literally no tradeoff for the two things you describe. So you’re not making any sense.
No, you simply misread the comment.
