Greetings marioroy.

Indeed, I stand corrected. However, I think that 1nickt's point about it not doing any locking and solve the issue that Perl 6 has when updating a container from multiple threads at the same time, is not true. From the MCE::Shared documentation:

    # Locking is necessary when multiple workers update the same
    # element. The reason is that it may involve 2 trips to the
    # shared-manager process: fetch and store in this case.
 
    $mutex->enter( sub { $cnt += 1 } );

This implies to me that MCE::Shared suffers from exactly the same issues that Perl 6 has and which Jonathan so aptly describes in blog post. Or am I missing something?
