 ==== Required functionality ====
 Extracting the required functionality to leads to the following required additions:
   * [[rfc:functional-elements:call-iterator|class CallIterator]]: a simple iterator which walks over a traversable list (including arrays) and calls a specified method. The CallIterator might optionally gather the results
-  * function is_traversable(): Returns true if a list is traversable (Iterator/IteratorAggregate/array)
+  * [[rfc::functional-elements:is-traversable|function is_traversable()]]: Returns true if a list is traversable (Iterator/IteratorAggregate/array)
-  * function iterate(): Walks over a traversable list and does nothing
+  * [[rfc:functional-elements:iterate|function iterate()]]: Walks over a traversable list and does nothing
-  * function iterator_true(): Walks over a traversable list and assumes every element to be true
+  * function iterator_true(): Walks over a traversable list and assumes every element to be bool(true)
-  * function iterator_false(): Walks over a traversable list and assumes every element to be false
+  * function iterator_false(): Walks over a traversable list and assumes every element to be bool(false)
+==== Modified use cases ====
+=== UC-1: Iterating over an aggregation of objects ===
+<code php>
+iterate(new CallIterator($list, 'method'));
+</code>
+=== UC-2: Iterating over an aggregation of objects and keeping the results ===
+<code php>
+$result = iterate(new CallIterator($list, 'method'), true);
