I think a bigger one from what I have looked is the complexity of (en^de)code bytes around. I suspect if you could use UNION better and be the same as Enum in Rust you could do us a favor! Also I wish I could do this easily: enum Tag { Int, Bool } enum Data { Int(Vec<i32>), Bool(Vec<bool>) } struct Val { tag:Tag, data:Data } let n = val.as_i32::<Tag::Int>(&self) -> Vec<i32>
