According to this http://stackoverflow.com/questions/33727657/kotlin-and-immut... Kotlin does not support true immutability.
For immutability to be practical one would need to implement structural sharing in their collections otherwise copying would be prohibitively expensive.
This Java library seems to be trying to implement this. http://www.vavr.io/
Again, I am not saying that Kotlin does not support immutability, just trying to get to the bottom of the reality of it.
