Hi, Bruno. My reasoning for having these marker interfaces was that they might be a useful means of recognizing the commonality between the various interfaces depending on the number of arguments accepted.[1] I can't say that I have a specific use-case for this, however. Would some other nomenclature allow us to serve both purposes?
