This is much cleaner than the previous proposal, and cant wait to actually get to use this (as a framework author it literally makes me giddy). Like others, I slightly wonder what will happen in The Real World™ (as a framework consumer) but if things end up too restrictive, it can always be changed down the road I would expect…? > * Is the problem being addressed significant enough to warrant a change > to Swift?

This seems closer to Kotlin; not that I am much of a user of that language so maybe I am unqualified to say, but I think its nice to align with a good design that exists elsewhere… Objc is of course the exact opposite of this, so it remains to be seen what the effect will be in this community... > * How much effort did you put into your review? A glance, a quick > reading, or an in-depth study? Been following this intensely since last year’s initial discussion, finally came out of the shadows to comment when it came up for review, and have been weighing and listening to arguments for and against; my only "against" feelings came about as a consumer of APIs not as a writer, so I want to make sure its apparent that any negatives I had in the past were from that perspective; I very much support the spirit of this proposal and appreciate those that took time to explain and assuage those concerns! What an amazing process this is. ^o^ ----------- One thing in the proposal: The superclass of an open class must be open. <snip/>. These are conservative restrictions that reduce the scope of this proposal; it will be possible to revisit them in a later proposal. Yes, maybe its an anit-pattern, but I definitely have made many private parent classes and have the child public… the above would mean that I cant do that, as open needs public… it would definitely be appreciated if that is revisited or at least the reasoning (e.g we really shouldn't be making subclasses of private superclasses public because XYZABC etc). ----------- Thanks!! > More information about the Swift evolution process is available at > > https://github.com/apple/swift-evolution/blob/master/process.md > > Thank you, > > -Chris Lattner > Review Manager > > > _______________________________________________ > swift-evolution mailing list > swift-evolution@swift.org > https://lists.swift.org/mailman/listinfo/swift-evolution
