If you mean that you install a __DIE__ handler, then what you do inside
is really your problem - __DIE__ will be called each time an exception
will be thrown, not when perl dies with an error (see perlvar for more
If you only want to die when perl is going to die itself, then you need
to walk up the callstack with caller and see if you are within an eval
context. And ignore anything else that should be ignored. How to detetc
this is up to you.
When in doubt, leave your hands off __DIE__, it's not for the faint of
