> When creating potential examples for the Groovy 5 release notes, I created
> this example:
> {code:groovy}
> // keep top 5 scores in top array
> int[] scores = [56, 82, 70, 74, 63, 92, 49, 69, 85, 79, 80, 82, 99, 95]
> int[] top = scores[0..4].sort()
> scores[5..-1].each { next ->
> def ins = top.partitionPoint{ it < next } - 1
> if (ins > 0) {
> System.arraycopy(top, 1, top, 0, ins)
> // top[0..<ins] = top[1..ins]
> }
> if (ins >= 0) {
> top[ins] = next
> }
> }
> assert top == [82, 85, 92, 95, 99]
> {code}
> The {{System.arraycopy()}} line would be {{top[0..<ins] = top[1..ins]}} if
> using lists. It would be nice if arrays supported putAt and that line didn't
> need to change.
