A warn or die handler is passed the argument to either warn or die. So if you have: 
$SIG{__DIE__} = sub { print "Died with message '$_[0]'\n"; };
open(NOFILE, '/no/file/here') or die "Ooops: $!";

then you will get: 
Died with message 'Ooops: No such file or directory at /home/stephen/t
+est.pl line 2.
'

[download]

Make sure you don't forget the double underscores before and after WARN and DIE, or you won't catch anything at all.

See perlman:perlvar for more information on %SIG. See perlfunc:warn and perlfunc:die for trapping warn and die.
