We have recently removed the f_yieldfrom field from the frame object. (http://bugs.python.org/issue14230)
Hey, wait a minute. Did anyone consider the performance effect of that change on deeply nested yield-froms? The way it was, a yield-from chain was traversed by a very tight C loop that found the end frame and resumed it directly. If I understand what you've done correctly, now it has to enter and execute a bytecode in every frame along the way. -- Greg _______________________________________________ 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
