It's certainly a powerful option to have. Java, for example, does allow an exception class to take such actions within its constructor and can choose not to trace the stack. It can't cancel itself -- you need to use an extra method call & layer of abstraction to get that effect. But that flexibility obviously comes with complexity. If people find it hard to trace the flow of control in the presence of exceptions, it can't be any easier when exceptions might or might not jump anywhere. _______________________________________________ Boston-pm mailing list [email protected] http://mail.pm.org/mailman/listinfo/boston-pm
