See Guido's answer. I don't think it's documented anywhere, but you can find the relevant code somewhere in Objects/typeobject.c (it's quite a mouthful, though :-)). (IIRC, "layout" is determined by tp_basicsize, tp_itemsize, the number of __slots__, and other things perhaps) Regards Antoine. _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
