...]int, fn func(int) bool) []int {

Why is Java's AbstractList's removeRange() method protected?
Does anyone have any idea, why removeRange method in AbstractList (and also in ArrayList ) is protected ? It looks like a quite well-defined and useful operation, but still, to use it, we're forced to subclass the List implementation.
