In comp.lang.perl.misc it was asked (message-ID: <email@example.com>)
I've tried various cloning modules to clone a structure containing weak
I've tried it using the Clone module and Clone::PP. Clone::PP does the
same as Storable. Clone gives a segmentation fault.
I'm using Perl 5.8.0 on Linux 2.4.20-8
use Storable 'dclone';
use Scalar::Util qw(weaken isweak);
my $x = 99;
my $y = [ \$x ] ;
$z = dclone $y;
print "y: ", isweak $y->;
print "z: ", isweak $z->;
my reply is
After a little bit of thought I'd say that's normal, to be expected
You're not cloning the weakend reference, but the the data it references,
the reference in z, poiting to the clone of $x, is a completly new one,
the data is cloned, not the reference.
I may misunderstand the behaviour though...hmmm
Now I'm curious: Am I right? And if I'm right: Is it possible to clone references (Update preserving their "weakend-state")?
