I keep noticing threads where people are confused about this kind of thing—I’ve seen it with Array, Optional, and several others. I wonder if these kinds of types simply *shouldn’t* offer .description properties, as a way of saying “no user-visible conversion inside”. -- Brent Royal-Gordon Architechies _______________________________________________ swift-dev mailing list swift-dev@swift.org https://lists.swift.org/mailman/listinfo/swift-dev
