/// @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.
