+Methods take a special first parameter, of which there are three variants:
 `self`, `&self`, and `&mut self`. You can think of this first parameter as
 being the `foo` in `foo.bar()`. The three variants correspond to the three
 kinds of things `foo` could be: `self` if it’s just a value on the stack,
 `&self` if it’s a reference, and `&mut self` if it’s a mutable reference.
