I faced an interesting scenario:
Splitting a stream into two, working with them separately, and then zipping them in the initial order
For now I do:

val (As, Bs) = list.mapIndexed { i, it -> Pair(it, i) }.partition { condition(it) }
    
  val Cs = As. map {..}.filter{..}.sortBy{..}

  return (As + Cs).sortedBy {it.second}.map {it.first}

I want a way to generalise it somehow
