Dear monks,

I accidentally tried to assign a non-existing function to $SIG{__DIE__}. It took some time to find that bug, because perl did not emit any warnings or errors.

My code, stripped down to show the problem:

#!/usr/bin/perl -T -w

use strict;
use warnings;

$SIG{'__DIE__'}=\&noSuchFunction;
print "You should not see this text\n"; # but you will!

Is it a bug in perl (v5.8.8)? I think I should not be able to create and assign a reference to a non-existing function, at least not with strict and warnings enabled.

Using 'noSuchFunction' instead of \&noSuchFunction did not help (and is not recommended in perlvar.pod), only *noSuchFunction generated a warning.

Thanks!
