Idiom #290 Sort sublist

Sort the part of the list items from index i (included) to index j (excluded), in place, using the comparator c.

Elements before i and after j must remain unchanged.

items[i..j] = items[i..j].sort_by{|el| c(el) }

c should result in something comparable, so it is determinable if one result is larger, equal or smaller than another result.
items.setRange(i, j, items.sublist(i, j)..sort(c));
