[BUG] @derive(Eq) is confusing

**Describe the bug**
```c
@derive(Eq)
enum MyEnum {
    One,
    Two,
}

fn cmp_enum() -> bool {
    let one = MyEnum::One();
    let two = MyEnum::Two();
    return one == two;
}
```

I can't simply do `one == two` because it transpiles to `eq(&one, two)` instead of `eq(&one, &two)`.

Is it intended that I have to do `one == &two` every time?
