    Async Generator Function Definitions

    AsyncGeneratorDeclaration:
      async [no LineTerminator here] function * BindingIdentifier ( FormalParameters ) {
        AsyncGeneratorBody }


    YieldExpression: yield * AssignmentExpression

    1. Let exprRef be the result of evaluating AssignmentExpression.
    2. Let value be ? GetValue(exprRef).
    3. Let generatorKind be ! GetGeneratorKind().
    4. Let iterator be ? GetIterator(value, generatorKind).
    ...

    GetIterator ( obj [ , hint ] )

    ...
    3. If hint is async,
      a. Set method to ? GetMethod(obj, @@asyncIterator).
    ...
    6. Let iterator be ? Call(method, obj).
    7. If Type(iterator) is not Object, throw a TypeError exception.
