> I *think* the feature you’re trying to use is on the todo list for Swift 3, but the last time I said that, I was completely wrong. The swift-evolution mailing list probably has more information.
I think it's on the list of things they'd like to do to generics in the future, but it's a very long list and they might not get to that particular one.
In short, though, my understanding is that there is no principled reason for this limitation; it simply isn't supported yet.
