Here is an example of what I’m trying to do: https://gist.github.com/deinspanjer/8a677933f5b85135b05a597c7fbc298c

deinspanjer: A couple of things: one is that it’s easier for people to help you if you paste code inline with triple backticks (`x3) (if you have a lot of code to paste, you can use command-enter). If you need to return a reference to a function, you can always return a new lambda that has the same signature and just calls the function you really want to call. For example:

fun example(s: String): String {
  return doSomethingWithS(s)
}

//effectively returns a method reference to "example"
fun returnsClosure(): (String) -> String {
  return { s: String -> example(s) }
}

Thank you!
