It's three allocations vs. one. The first is tuple + str + int, while the adapter is just one object. I'm not sure how it eventually shakes out, though. That said, it's still worse than Python 2, which is zero allocations. :) Reid _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
