How to declare a generic class in Kotlin that simultaneously extends a class and implements an interface?
Hi everyone! I started learning Kotlin after Java and encountered a confusing situation. In Java, I could easily write a generic class that simultaneously extends some base class and implements an interface:
```java
public class MyClass {
// ...
}
```

```kotlin
open class BaseClass
interface MyInterface

class MyClass where T : BaseClass, T : MyInterface
// Attempt 2: also doesn't work
class MyClass // Error!
```
