[swift-evolution] [Pitch] Property reflection

[Austin Zheng]

Would you be willing to elaborate? Are you thinking of model objects whose properties are all completely hidden using 'private' and whose APIs are available only through methods? What if there existed something like "private(reflectable)", for properties you really want to keep both private and exposed to the reflection machinery? Or maybe a property behavior to do the same thing once that feature becomes a reality...
