Hey folks, I was wondering, what mechanism in Kotlin allows that java.util.LinkedHashMap<Int,Int> somehow implements kotlin.collections.Map<Int,Int>? Is there scala-style implicit conversion / wrapping going on?

val lhm: kotlin.collections.Map<Int, Int> = java.util.LinkedHashMap()

I can tell you no wrapping is involved.

It's "compiler magic":

damn that is brilliant, that's much more integrated into the host language than the scala collections are
