I'm not sure this topic is settled at all (felt a bit more like deferred I thought). But this may well turn out to be the case. There is some circularity either way of course - one will probably be defined in terms of the other. The more important point is that Swift does have structural types and even if you could define Tuple with variadic generics you still have structural function types. So it will always have at least one structural type. > > -- > Brent Royal-Gordon > Architechies > _______________________________________________ swift-evolution mailing list [email protected] https://lists.swift.org/mailman/listinfo/swift-evolution
