That's pretty amazing. > It would be unfortunate for PyPy (and IMHO, very un-pythonic) if this > process became impossible. Not a problem. func_closure is already a restricted attribute. IMHO, the clean way to do this is to provide a built-in function to get the cell content in a more direct and reliable way, and then put that in a separate module with other interpreter hacks. That both makes it easier to do stuff like this, and easier to prevent it simply by forbidding import of that module. -- ?!ng _______________________________________________ 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
