+    AsyncGeneratorMethod :

+    1. Let propKey be the result of evaluating PropertyName.

+    3. If the function code for this AsyncGeneratorMethod is strict mode code, let strict be true.
+       Otherwise let strict be false.
+    4. Let scope be the running execution context's LexicalEnvironment.
+    5. Let closure be ! AsyncGeneratorFunctionCreate(Method, UniqueFormalParameters,
+       AsyncGeneratorBody, scope, strict).

+    1. Return the result of performing IteratorBindingInitialization for BindingElement with arguments iteratorRecord and environment.
