Hi, I wrote an article about Kotlin & WatchService - an example how to wrap existing Java API with Kotlin - a practical use of some language features such as: extensions, channels, sealed classes & implementation by delegation.

This was pretty neat, I'm just not sure I agree with your use of sealed classes. The way you used them (entirely constant) seems like you'd be better off with enums.

Good point. I want to believe though we only have enums in Kotlin because of the Java inter-op 🙂

Enums are syntactically shorter and much lighter in terms of VM.

guess it might be an overkill, gonna update that

fixed, thanks for feedback
