If you happen to have an already-initialized value `foo`, yes, but you wouldn't be able to initialize a value this way. That would require knowing that some assigning to some set of key paths will fully initialize a value. That's something we'd like to support in some way eventually, but not as part of this first proposal. -Joe _______________________________________________ swift-evolution mailing list [email protected] https://lists.swift.org/mailman/listinfo/swift-evolution
