### What it does
Detects enumeration variants that are prefixed or suffixed
by the same characters.
### Why is this bad?
Enumeration variant names should specify their variant,
not repeat the enumeration name.
### Limitations
Characters with no casing will be considered when comparing prefixes/suffixes
This applies to numbers and non-ascii characters without casing
e.g. `Foo1` and `Foo2` is considered to have different prefixes
(the prefixes are `Foo1` and `Foo2` respectively), as also `Bar螃`, `Bar蟹`
### Example
```
enum Cake {
BlackForestCake,
HummingbirdCake,
BattenbergCake,
}
```
Use instead:
```
enum Cake {
BlackForest,
Hummingbird,
Battenberg,
}
```
