+    1. Let rhs be the result of evaluating Initializer.
+    2. Let value be GetValue(rhs).
+    3. ReturnIfAbrupt(value).
+    4. Let env be the running execution context's LexicalEnvironment.
+    5. Return the result of performing BindingInitialization for BindingPattern
+       using value and env as the arguments.

+    13.3.3.6 Runtime Semantics: IteratorBindingInitialization
+    ArrayBindingPattern : [ Elisionopt BindingRestElement ]
+    1. If Elision is present, then
+       a. Let status be the result of performing
+          IteratorDestructuringAssignmentEvaluation of Elision with
+          iteratorRecord as the argument.
+       b. ReturnIfAbrupt(status).
+    2. Return the result of performing IteratorBindingInitialization for
+       BindingRestElement with iteratorRecord and environment as arguments.
