| AsyncGeneratorMethod : |
| async [no LineTerminator here] * PropertyName ( UniqueFormalParameters ) |
| { AsyncGeneratorBody } |
| |
| 1. Let propKey be the result of evaluating PropertyName. |
| 2. ReturnIfAbrupt(propKey). |
| 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. Let status be the result of performing BindingInitialization for |
| BindingPropertyList using value and environment as arguments. |
