     N.B., due to the structure of AppEngine pipelines, this method must
     accept the same arguments as are passed to ``__init__``; however,
     because they were already passed to ``__init__`` there's no use in
     recieving them here. Thus, we discard all the arguments to this method
     (except for ``self``, naturally).
