This is another attempt, where the decorator is a still a class but uses an auxiliary function: http://paste.chrisarndt.de/paste/38bf8a8443614464968d424e1f2d4182 However, that raises this exception: http://paste.chrisarndt.de/paste/f90bc9a058254e2ca5660882011752a7?wrap=no -- http://mail.python.org/mailman/listinfo/python-list
