Please remember that stored properties can be overridden in Swift:

class Base {
  /*instance*/ var flag: Bool = true

class Sub : Base {
  override var flag: Bool {
    didSet {
      if flag { print("The flag was set!") }

This is theoretically possible at the class level as well, but doesn't really make sense for what's currently spelled "static var", since you'd be accessing the same storage in different ways. Does the proposal mean that a stored "type var" is non-overrideable, but a computed "type var" is overrideable, implicitly?
