What about the object variant safety issue? 
    
    
    type
      DocKind = enum
        text,
        todo
      
      Doc = object
        case kind: DocKind
        of text:
          text: string
        of todo:
          todo: string
    
    let doc = Doc(kind: text, text: "some doc")
    echo doc.todo#compiles, throws exception
    
    
    Run

As far as I can tell, preventing this generally would require forbidding access 
of variant fields when not inside a `case kind` typeguard.

Would that tradeoff between flexibility and safety be desirable?
