        self.referenceToSomeTypeImplementingProtocol = referenceToSomeTypeImplementingProtocol
    }

    override func main() {

    }
}

class TypeImplementingSomeProtocol: SomeProtocol {


    init() {

    }
}


let operationQueue = NSOperationQueue()

let typeImplementingSomeProtocolInstance = TypeImplementingSomeProtocol()


let operation = GenericOperation(referenceToSomeTypeImplementingProtocol: typeImplementingSomeProtocolInstance)


operationQueue.addOperation(operation)
