I'm searching for the syntax to do pattern matching with multiple cases in an if case statement.
The example would be this:

```
enum Gender {
    case Male, Female, Transgender
}

let a = Gender.Male

```

Now I want to check, if a is .Male OR .Female. But I would like to avoid using switch for this. However the switch statement would be like this:

```
switch a {
case .Male, .Female:
    // do something
}

```

Is it possible to write this with if case?
I would expect this, but it didn't work :(

```
if case .Male, .Female = a {

}

```
