Yes, this is why I distinguished between lob and throw, and said:

The idea is that sometimes you definitely want to throw an error - there's no way to continue. On the other hand, you might just want to lob an error back to the caller, and let them decide if they want to go on.

In other words, if the subroutine throws an exception, you can't bounce it back. But if it lobs one, you can. Obviously, letting user code ignore serious errors would be foolish.

You could do it by argument-passing, just as you can do exception throwing by returning undef and letting the caller decide whether to die. But that doesn't mean exception-throwing isn't better. The advantage of this is that different calling code can decide to bounce different classes of exceptions. Just like try ... catch, it gives you more fine-grained control.
