Is there a reason why file.readlines() doesn't/can't return an iterator?

This is problably too late and I'm probably missing something but given amount of generators/iterators introduced in python 3.X (http://docs.python.org/release/3.0.1/whatsnew/3.0.html#views-and-iterators-…) file.readlines() seems a good case where an iterator can be more appropriate than a list. I realized it while writing this recipe: http://code.activestate.com/recipes/577968-log-watcher-tail-f-log/ In this specific case, having readlines() yield a single line at a time would save a lot of memory. Maybe we can introduce a new parameter to do this? Regards, --- Giampaolo http://code.google.com/p/pyftpdlib/ http://code.google.com/p/psutil/
