Hi swift-evolution, I was wondering if anything more detailed has been written about generalized existentials / type erasers. I noticed that AnyCollection only delegates a number of methods to its wrapped value, but often doesn't. For example, all the conditionally inherited items aren't being delegated (e.g. min()). This behavior was surprising to me (but makes sense once I thought about it longer).
How would this work with generalized existentials? Are generalized existentials in scope at all for Swift 4? -- Chris Eidhof
