in thread Deprecated use of $SIG{__DIE__} is useful

Overriding die catches calls to die('Error'), but it doesn't catch errors such as undefined values being thrown because I've used strict.

In situations like this, where your code behaves in an unexpected way, it is useful to have a stack trace to see how we got to that point in the code, which I can only do with $SIG{__DIE__}.

Overriding die catches calls to die('Error'), but it doesn't catch errors such as undefined values being thrown because I've used strict. Neither does $SIG{__DIE__}. That would be $SIG{__WARN__}.	[reply]

I'm not sure what he meant by throwing undefined values, but that which strict produces is caught by `$SIG{__DIE__}`, not `$SIG{__WARN__}`.	[reply] [d/l] [select]

Yeah, I guess that could go either way, since undefined variables are not something that would be caught by strict.	[reply]
