I think you're slightly confused. All Collections have an Index. Dictionary's Index is not its Key; it is an opaque type which references an entry in its internal table. Set also has an Index; again, it is an opaque type which references an entry in its internal table. Your `enumerate()` (or my `indexed()`) would return these opaque `Index`es on all of these types. If you want Array to return `(Int, Element)`, Dictionary to return `(Key, Value)`, and Set to not have the operation at all, you're describing something ad-hoc and entirely disconnected from the Collection type. -- Brent Royal-Gordon Architechies _______________________________________________ swift-evolution mailing list swift-evolution@swift.org https://lists.swift.org/mailman/listinfo/swift-evolution
