Indeed, it's not the hodgepodge that many people believe it to be, it just comes from a heritage that's much further away in the PL family tree than they're used to. There are something things which were grafted on to S/R later on. For instance the S4 OOP system was added much later (in S4) and was based on Dylan's OOP system. So there's a case where the GP is correct that it was taking structure from another PL but it's also one which is fairly foreign to a lot of OOP devs
