[swift-evolution] [Proposal] Enums with stored properties

[Mateusz Malczak]

For simple structs this is already possible (see this example:
https://swiftlang.ng.bluemix.net/#/repl/57fb8e3e4f9bcf25fdd415cd).
If we focus on more complex cases where properties of Any? type are
allowed I think this approach could do the trick...
but still I would like to be able to access properties without using rawValue
