 * @assertion Iterable<E> skipWhile(bool test(E value))

 * The returned iterable provides elements by iterating this iterable, but
 * skipping over all initial elements where test(element) returns true. If all
 * elements satisfy test the resulting iterable is empty, otherwise it iterates
 * the remaining elements in their original order, starting with the first
 * element for which test(element) returns false.
 * @description Checks that if not all elements satisfy the test, the returned
 * iterable iterates the remaining elements in their original order, starting
