  I decided to take the Moose out for a test drive, and ran into:
  
  has 'count' => (is=>'rw', isa=>'Int');
  
  $thing->count++; # fails!
  $thing->count($thing->count + 1); # ugly!
  
  Are lvalue accessors considered harmful, or would this make a good Moose::Policy?

    Yes, lvalue accessors are pretty useless in the real world. That's because you don't get a chance to intercept the value that's being assigned to. You can't (say) step in and clone something before it's assigned.

      Unless, of course, you return a tied value…

      Somehow, it feels like this discussion has already happened a couple times before…

        Very true, but it does start to feel like a lot of work that could be sidestepped by using a mnore traditional approach.
