Hey I am a noob learning Kotlin and I don't know Java. Can someone help me understand the difference between sealed classes and enums? Am I  right in assuming enums are like singleton sealed classes?

- sealed classes mean a class cannot be _inherited_ beside those already declared in the same file (if i remember well)
- enums are well, enumerations, like value types from the same type. and yes, they are singletons

All right. That makes it a bit clearer. So if I want I can use sealed classes like enums too, right?

Well lets say I want to implement a Msg type, where it sends a subtype `Err` if it receives an `Err` or sends a subtype `NewMsg(text : String)` when it receives a new message
