But Lisp isn't dynamically typed "exactly the way Python is". Python documents ways to manipulate the internals of objects at runtime. It is possible to add, change or delete methods and slots by directly changing the hashtable they're stored in. While CLOS does permit a certain amount of runtime redefinition, it is not as completely free wheeling and unpredicatable. -- http://mail.python.org/mailman/listinfo/python-list
