+// TODO: Let's start sketching our ticket store!
+//  First task: implement `IntoIterator` on `TicketStore` to allow iterating over all the tickets
+//  it contains using a `for` loop.
+//
+// Hint: you shouldn't have to implement the `Iterator` trait in this case.
+//   You want to *delegate* the iteration to the `Vec<Ticket>` field in `TicketStore`.
+//   Look at the standard library documentation for `Vec` to find the right type
+//   to return from `into_iter`.
