Nim boilerplate

[Calonger]

@aEverr says correcet , your concept is recursive make no sense.
    
    
    type
      CircleShape = concept a
        buildCircleProps(a)
    proc buildCircleProps[T](a: T) = discard
    
    proc buildCircleProps(a: CircleShape) = ...
    
    
    Run

Wrong ! Remove buildCircleProps from concept and generic buildCircleProps . 
buildCircleProps defined on CircleShape enough .
