+    Set ( [ iterable ] )
+
+    When the Set function is called with optional argument iterable the following steps are taken:
+
+    ...
+    7. Else,
+      a. Let adder be Get(set, "add").
+      b. ReturnIfAbrupt(adder).
+      c. If IsCallable(adder) is false, throw a TypeError exception.
+      d. Let iter be GetIterator(iterable).
+      e. ReturnIfAbrupt(iter).
+    ...
+    9. Repeat
+      a. Let next be IteratorStep(iter).
+      b. ReturnIfAbrupt(next).
+      c. If next is false, return set.
+      d. Let nextValue be IteratorValue(next).
+      e. ReturnIfAbrupt(nextValue).
+      f. Let status be Call(adder, set, «nextValue.[[value]]»).
+      g. If status is an abrupt completion, return IteratorClose(iter, status).
