I've wanted that a few times, frequently in a situation where I'm doing validity checking, and I either want to continue after calling a validity check or return immediately with some kind of error object. For example: returnif self.isitaboojum(snark) This works nicely if the checking routine either returns False or an error object. It also works if the method is doing some kind of a ladder evaluation of several distinct conditions, and it wants to return the first one it finds. Also, I wouldn't want a returnif in a loop. Following on with this idea, loop control would be more of a breakif or continueif statement. John Roth -- http://mail.python.org/mailman/listinfo/python-list
