public final class InGroupsOf<A>
extends java.lang.Object
implements Fn2<java.lang.Integer,java.lang.Iterable<A>,java.lang.Iterable<java.lang.Iterable<A>>>

Lazily group the Iterable by returning an Iterable of smaller Iterables of size k. Note that groups are not padded; that is, if k >= n, where n is the number of remaining elements, the final Iterable will have only n elements.
