   public var bar: Int { return 1 }
}


extension Foo {
   private var bar: Int { return 1 }
   public var baz: Int { return 1 }
}


extension Foo {
   private var bar: Int { return 1 }
   public func baz() {}
}


extension Foo {
   var bar: Int { return 1 }
   var baz: Int { return 1 }
}


public extension Foo {
   var bar: Int { return 1 }
   var baz: Int { return 1 }
}


extension Foo {
   private bar: Int { return 1 }
   private baz: Int { return 1 }
}


extension Foo {
   open bar: Int { return 1 }
   open baz: Int { return 1 }
