Because it encourages harmful laziness. Laziness is only a virtue when it leads to good code for little effort, but in this case, it leads to non- portable code. Worse, if your data structures include cycles, it also leads to resource leaks. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
