in reply to Using ArrayRef data members in Moose

This isn't really a Moose issue, it's a Perl one. push and pop must take an array, not an array reference. So you'll need to dereference the arrayref to use those functions on it. You could easily add a method to wrap push and pop, but that seems kinda lame.

There's MooseX::AttributeHelpers::Collection::Array, which certainly sounds like it would be useful, but it beats the hell outta me what it does. Unfortunately I'm quite the Moose n00b myself.

    True.

    By way of contrast, I figured out the sugar for using HashRefs. Hit on this by "genetic programming" -- trying different things until something worked:

    $obj->count_by_word()->{$word} = $count;
    It would be great if there was something similarly simple for arrayref access -- I'm suspecting that there is, and I just haven't found it.
      I think that it works quite the same with arrayrefs:
      $obj->weight()->[0] = 10;
      By way of contrast, I figured out the sugar for using HashRefs.

      This is not sugar at all, this is just how HASH refs work. The "count_by_word" accessor is simply returning the HASH ref value that is stored, nothing more nothing less.

      -stvn
        Ah, yes. Now I get it. Thanks.

        And thanks also to karavelov for the example.
