    AsyncMethod : async PropertyName ( UniqueFormalParameters ) { AsyncFunctionBody }

    1. Let propKey be the result of evaluating PropertyName.
    2. ReturnIfAbrupt(propKey).
    3. If the function code for this AsyncMethod is strict mode code, let strict be true. Otherwise
       let strict be false.
