It's more likely you'd circumvent the assumptions. That is, find an 'outside-the-box' solution. For instance, a deeply parallel architecture could escape the assumption that you can only compare two numbers at a time (per step). The proof's conclusion is still true if its assumption is. -- http://mail.python.org/mailman/listinfo/python-list
