|     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).
