[swift-users] Why can't structs inherit from other structs?

Sometimes, this would be very handy (not only for structs) — but I'd expect that there are at least as many cases where you don't want that behavior…
It would be possible to silently generate readwrite-properties (and even functions returning void or an optional), but that feels a little bit to much magic for me.

Also, this would be a use-case for protocols that is completely different from their normal role.
