Renaming an enum

First off – love this guide!

I see the note about adding or renaming fields in an enum. I'm wondering about changing the name of an enum. For example:

```
enum Status = {
  PRIVATE = 0,
  PUBLIC = 1
};
```

Becomes:
```
enum Visibility = {
  PRIVATE = 0,
  PUBLIC = 1
};
```

Same exact field names and values, just a enum name change. Any chance this can be added to the guide?
