in thread unreachable memory with a non-zero reference count

But that way you lose the old value. I'm not sure that that's really what you want:

#!perl -w
use strict;
use Data::Dumper;
my $foo = 'bar';
$foo = \$foo;

print $foo;
print $$foo;
print Dumper $foo;

__END__

REF(0x12da554)
REF(0x12da554)
$VAR1 = \$VAR1;

    Of course it isn't. :-) I thought I would be actually using code like in my example and therefore I thought it would be working, but this doesn't seem to be the case. I can't find it anymore, seems I've rewritten it before running into the problem shown and couldnt' remeber anymore. Seems I now have to reasons for don't using things like that, thanks. :-)
