Do you have a compelling use case?
There's a big difference between "not enough memory" and "directory consumes lots of memory". My company has some directories with several hundred thousand entries, so using an iterator would be appreciated (although by the time we upgrade to Python 3.x, we probably will have fixed that architecture). But even then, we're talking tens of megabytes at worst, so it's not a killer -- just painful. -- Aahz ([EMAIL PROTECTED]) <*> http://www.pythoncraft.com/ Help a hearing-impaired person: http://rule6.info/hearing.html _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
