In the spec it says "Return true if successful, false otherwise (e.g., D is an invalid argument)". If D is null, would this count as an invalid argument or would this be successful since there is technically nothing left to destroy? If this does not count as an invalid argument, then I'm confused as to what would count as one in this function.
