+ * @author Krzysztof Krason (Krzysztof.Krason@gmail.com)

+ * @since 0.31
+ * @todo #814:30min Implement immutable ListIterator and Iterator that should
+ *  be returned from ListEnvelope when calling `listIterator` and `iterator`
+ *  methods. After those are implemented remove `@Ignore` from the tests below
+ *  - all of them should pass after the change.
