+description: IteratorClose is invoked when evaluation of AssignmentElementList returns a "throw" completion and the iterator has not been marked as "done" (AssignmentExpression)

+    1. Let rhs be the result of evaluating Initializer.

+    3. ReturnIfAbrupt(rval).
+    4. Return the result of performing BindingInitialization for

+    4. Let status be the result of performing
+       IteratorDestructuringAssignmentEvaluation of AssignmentElementList using

+    5. If status is an abrupt completion, then
