[swift-evolution] Proposal: Contiguous Variables (A.K.A. Fixed Sized Array Type)

If n is a variable whose value is determined at runtime, the compiler can't enforce type safety. It is no problem to declare structures of fixed size in Swift, so there is no need for a special syntax unless it has benefits (like improved safety).
