 //@ In Rust, adding a destructor for a type is done by implementing the `Drop` trait. This is a very special trait.
 //@ It can only be implemented for *nominal types*, i.e., you cannot implement `Drop` for `&mut T`. You also cannot
 //@ restrict the type and lifetime parameters further than the type does - the `Drop` implementation has to apply to *all* instances
