That's not the same thing as Georg is talking about, IIUC. The exception()
method is used in exception *handler* code to record that the exception
occurred, but the correct thing for any code to do when an error condition is
detected (in most situations at least) is to raise an exception. It would be
quite wrong for code to e.g. call logger.error(...) instead of raise ...
