Any easy way to compare `==` object variants?

[alexeypetrushin]

Seems like `==` operator doesn't work for object variants. Is there better 
options than writing it by hands?

Writing `==` proc manually feels a bit o
    
    
    type
      Obj = object
        case type: bool
        
        of false:
          a: int
        
        of true:
          b: int
    
    echo Obj() == Obj() # Error
    
    
    Run

P.S.

There's an option to convert objects to json and compare string blobs for 
equality, not good for performance, but still better than writing comparison 
code manually :).
