+// The `current_favorite_color` function is currently returning a string slice with the `'static`
+// lifetime. We know this because the data of the string lives in our code itself -- it doesn't
+// come from a file or user input or another program -- so it will live as long as our program
+// lives. But it is still a string slice. There's one way to create a `String` by converting a
+// string slice covered in the Strings chapter of the book, and another way that uses the `From`
+// trait.
