I don't see what's so inefficient about it necessarily. The key argument invokes a DSU scheme that allocates and releases potentially a lot of memory, which both uses time and increases the program's memory region. The cmp option should not be removed. However, requiring it to be specified as a keyword parameter instead of just passed as an unlabelled arg is fine. -- http://mail.python.org/mailman/listinfo/python-list
