Heh, everybody has one of two reactions: "This is awesome!" "You'll add type checking to my Python code over my dead body!!!" But I'm still to see a practical use for annotations in real world code. Or indeed to think of a use for them other than type checking. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
