Re^2: passing shared blessed object part 2

    One thought crossed my mind (but I'm not in a position to test it).

    I believe that the newer versions of threads::shared override bless in order to enable the new shared blessed refs facility. And whilst I have no direct knowledge that it does, it wouldn't surprise me if Moose or Class::MOP did the same thing for their own purposes. That could well account for (at least some) of the errors you see when you include both.

    It might be worth trying avoiding the conflict by invoking threads::shared::share() directly, rather than importing it. So something like: 

    use threads::shared ();
...

    $thread_hash{'twit'} = threads::shared::share( $twit );
...

    might provide a work around for the problems.

      Nope, Moose/MOP does not (and never will) override global behavior like that. The fact that threads::shared does means that might be the source of the problem right there.

        Fair dos. I only said it was a possibility for the cause of the conflict.

        It'd be interesting to see if Moose can interoperate with threads::shared in a sane fashion. I hope that the discussion (and the solution found if any), doesn't disappear into the IRC bitbucket along with so much other potentially useful wisdom.
