    Quote from threads::shared (Perl 5.8.3):

    "bless" is not supported on shared references. In the current version,
    "bless" will only bless the thread local reference and the blessing
    will not
    propagate to the other threads.

    In other words, it's not possible to share references to objects. I.e.
    following shouldn't work:

    package Foo::Bar;
    use threads;
    use threads::shared;
    sub new { my $self = &share( {} ); bless $self, shift; }
    sub zot { print "zot\n"; }

    my $foo = Foo::Bar->new;

    threads->create( sub {

    Is that a correct interpretation? Because the code example does actually
    without any problems.

    I also found a mail that indicates that blessing of sharede references
    indeed work:


    Umm... So I guess my question is: is it safe to share blessed references
    threads? :)
