Forward declaration of object name

[Lachu]

I need to forward declare of object name. I use c2nim and it generates code 
similar to below:
    
    
       #First file
       connection {.bycopy.} = object
       #New line
       #Second file
        connection* {.bycopy.} = object
          id*: cint
          sock*: cint
    
    
    Run
