but it is not really much of an object (at least, not in the sense that it's commonly used and understood by practitioners of Object-Oriented paradigm

Well - you get as much of an object as you give it. If you die with a string you get a string. If you die with an object you get an object. We don't have a specialised exception class - but that's the way Perl 5 is in general :)

Are you saying that if I `eval { die MyExceptionClass->new(...) };` that the `$@` variable will contain the instance of MyExceptionClass? Wow. It never dawned on me that that might be the case... This changes everything! [Jon]	[reply] [d/l] [select]

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.	[reply]

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]
