What would be the best way to set the default size for Iterable extension functions like map where I have an Iterable that is not a Collection but I know its size? Is there any chance something like that could get added to the std lib?

inline fun <T, R> Iterable<T>.map(defaultSize: Int = 10, transform: (T) -> R): List<R> {
  return mapTo(ArrayList<R>(collectionSizeOrDefault(defaultSize)), transform)
}
