Is there a set of Koans for people who don’t know java ? I’ve just hit a point in the Koans where the suggested reading before working on a Koan would be just about impenetrable for someone who only knows (say) ruby. I’m talking about i_introduction._12_Extensions_On_Collections which sends you to https://kotlinlang.org/docs/reference/collections.html

The only reason I can make any headway on this is I happen to have found out yesterday that List<Int> relates to a concept called generics (I think) which I can google. Without that knowledge I’d be snookered. This isn’t the only example either, but it is the worst yet.
