in thread Use of "die" in OO modules

Are you saying that if I eval { die MyExceptionClass->new(...) }; that the $@ variable will contain the instance of MyExceptionClass?

Exactly ;-) From perldoc die:

die() can also be called with a reference argument. If this happens to be trapped within an eval(), $@ contains the reference. This behavior permits a more elaborate exception handling implementation using objects that maintain arbitrary state about the nature of the exception. Such a scheme is sometimes preferable to matching particular string values of $@ using regular expressions.

Awesome.. I tried it and I like it! Now I just wish that something like this: `catch (ThisClass $e) {...} catch (ThatClass $e) {...}` [download] was built into Perl!! [Jon]	[reply] [d/l]

Exception::Class::TryCatch is one non-core approach.	[reply]
