/// @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.operator== of the element.
/// Some types of iterable may have a different equality used for its elements.
/// For example, a Set may have a custom equality (see Set.identical) that its
/// contains uses. Likewise the Iterable returned by a Map.keys call should use
/// the same equality that the Map uses for keys.
/// @description Checks that true is returned if the collection contains
/// an element equal to element, false otherwise.
