I want to use Moose system in a project that requires threaded programming, and share object between threads. So I attempted to create an object that is shared, using Moose's "BUILD" mechanism. And I hope that any classes extending this one will be automatically sharing-friendly classes. 
use strict;
use threads;
use threads::shared;

{

    package ThreadableObj;
    use Moose;
    use threads::shared;
    use Data::Dump qw/dump/;

    sub BUILD {
        my $self = shift;

        # here the blessed() already be the version in threads::shared
        bless shared_clone($self), ref($self);
        print dump($self),"\n";

        return $self;
    }

    has foo => ( is => 'rw', isa => 'Str' );
    has bar => ( is => 'rw', isa => 'Int' )
}

# here dies
my $obj : shared = ThreadableObj->new(foo=>'foovalue');

However, the constructed object is not shared, as shows in this error message: 
Invalid value for shared scalar at XXXXX

Moreover, the output of dump() is: 
bless({ bar => 123, foo => "foovalue" }, "ThreadableObj")

Any suggestions? Thanks a lot!
