@utils.positional(<NUM_LIT:2>)<EOL><INDENT>def count(self, limit=None, **q_options):<DEDENT>
return self.count_async(limit, **q_options).get_result()<EOL>
Count the number of query results, up to a limit.

        This returns the same result as len(q.fetch(limit)) but more

          **q_options: All query options keyword arguments are supported.

        Returns:
