I wouldn't call it a "limitation"; it's a designed behavior which is the right thing for some purposes and maybe not for others. For example, groupby (as currently defined) works properly on infinite sequences, but a version that scans the entire sequence to get bring together every occurrence of every key would fail in that situation. I agree that the doc description could be reworded slightly. -- http://mail.python.org/mailman/listinfo/python-list
