We have heard these horror tales about everyone making "everything DynamicLookupable" and this being extremely bad, but can anyone actually produce a believable example? It's not like it's absurdly convenient to implement this, the ergonomics are at the call site, not the implementation. It sounds like you think that just conforming to DynamicMemberLookupProtocol and DynamicCallable will magically make everything in the code dynamic with no extra effort. /Magnus _______________________________________________ swift-evolution mailing list swift-evolution@swift.org https://lists.swift.org/mailman/listinfo/swift-evolution
