[swift-evolution] [Proposal] Enums with static stored properties for each case

[Jānis Kiršteins]

As stated before it supposed to be per case initialization. You cannot
really have this analogy with other types as they have type and
instance while enums have type, case and instance. But consider this:

struct Struct {
    static let bezierPath: UIBezierPath // shared

    static func initialize() {
        bezierPath = UIBezierPath()
    }
}
