I'd call that a bug, not something requiring evolution discussion. We're trying to phase this behavior out of dynamic casts, though (see https://github.com/apple/swift-evolution/blob/master/proposals/0083-remove-bridging-from-dynamic-casts.md). -Joe _______________________________________________ swift-evolution mailing list swift-evolution@swift.org https://lists.swift.org/mailman/listinfo/swift-evolution
