 A minor mistake (such as a misspelling, leaving out a `const`, using `&` instead of `&&`, or leaving out a special function) can lead to errors or warnings.

 Because we defined the destructor, we must define the copy and move operations. The `= default` is the best and simplest way of doing that.
