Yes. Besides, I still think that string-based exceptions are just convenient for quick & dirty, throw-away test scripts.

They have a hard-to-understand quirk though: the id() of the string is used to check rather than its value, so that except "foo" doesn't necessarily catch raise "foo"; but due to various optimization, this usually works, and people get bent out of shape when it doesn't.

I sort-of use this feature when I'm debugging: if I want to know what happens in an exception that is usually caught somewhere higher up in the call stack I simply put quotes around the exception name and the exception will happen uncaught. The same trick works for except: clauses. -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen@oratrix.com | ++++ if you agree copy these lines to your sig ++++ www.oratrix.nl/~jack | see http://www.xs4all.nl/%7Etank/spg-l/sigaction.htm
