The namedtuple recipe by Raymond Hetting does exactly that and, guess what, it uses exec! Also the doctest module in the standard library uses exec at good effect. So, I would say it is not a 99% rule, let's say it is a 98% rule ;) BTW, I also write a paper on namedtuple which I am going to translate in English soon or later (for the moment there is Google Translator): http://stacktrace.it/articoli/2008/05/gestione-dei-record-python-1/ The paper, just as the namedtuple recipe, has a strong functional bias so it may be of interest to people coming from Scheme.
