/**
 * @assertion bool contains(Object element)
 * Returns true if the collection contains an element equal to element.
 * This operation will check each element in order for being equal to element,
 * unless it has a more efficient way to find an element equal to element.
 * The equality used to determine whether element is equal to an element of the
 * iterable defaults to the Object.== of the element.
 * @description Checks that true is returned if the collection contains an
 * element equal to [element], false otherwise.
