At def-execution time, presumably 6 (the two decorators w/o args, plus 2 each for those w/args); at call time, it depends what the decorators are doing (if each adds exactly one wrapping closure, for example, there will indeed be 5 nested calls). Unfortunately I do not know much of today's cherrypy internals, so I don't know what each decorator is doing internally. Alex -- http://mail.python.org/mailman/listinfo/python-list
