<E> forElementAndEachIn(E, Array/Iterable/Sequence<E>, action: (E) -> Unit)applies the given action tothisand each entry in Iterable -
Iterable<T>.forEachRemaining()shortcut forwhile(hasNext()) yourLambda(next()) -
Array/List.ifWithinBound shortcut for
if(index < size){ thenBlock() } else { elseBlock() } -

Installation
KBox is pusblished to maven central, jcenter and bintray. Following an example if you use gradle and jcenter:
repositories { jcenter() }
