Yes - you are right of course - this was just a minimal example of course to illustrate the sort of thing I'm using function attriutes for.

The main reason for using a decorator was to avoid problems like the following whilst providing an easy way of adding the attribute: >>> def assn_or_other(data): ... return False ... >>> # I want x to be treated as normal. ... x = assn_or_other >>> >>> # I want y to be an assertion ... y = assn_or_other >>> y.is_assertion = True >>> x.is_assertion True -- http://mail.python.org/mailman/listinfo/python-list
