Object Variant question

[georgelemon]

What about 7 fields instead of 9? :)
    
    
    type
      Node = object
        name, op: char
        val: int
        case nt: NodeType
        of BinaryNode:
          blidx, bridx: Natural
        of UnaryNode:
          ulidx: Natural
        else: discard
    
    
    Run
